Overview

Nidal Hasan is a U.S. citizen of Palestinian descent and a convicted domestic terrorist. In November 2009, while serving as a soldier at the Fort Hood military post in Kalleen, Texas, Hasan launched an attack on fellow soldiers, killing 13 people and wounding 32 others.Jennifer Hlad, “In opening remarks, Hasan says he was ‘on the wrong side’ in US Army uniform,” Stars and Stripes, August 6, 2013, https://archive.org/stream/final-report-of-the-william-h.-webster-commission#page/n0/mode/2up. In the year leading up to the attack, Hasan was in contact via email with al-Qaeda in the Arabian Peninsula (AQAP) cleric Anwar al-Awlaki, reportedly sending him a series of emails in 2008 and 2009 and receiving two emails from Awlaki in response.David Johnston and Scott Shane, “U.S. Knew of Suspect’s Tie to Radical Cleric,” New York Times, November 9, 2009, http://www.nytimes.com/2009/11/10/us/10inquire.html;

In his court hearings following the attack, Hasan claimed that he had targeted U.S. soldiers in order to preemptively protect Taliban militants in Afghanistan.Michael Muskal and Molly Hennessy-Fiske, “Maj.

Hasan pled not guilty to murder-related charges but was nonetheless convicted by a military jury and sentenced to death in August 2013.Chelsea J.

In March 2025, the U.S. Supreme Court declined to hear Hasan’s appeal, opening a path for the White House to approve the fulfillment of Hasan’s death sentence.https://www.kwtx.com/2025/09/25/he-doesnt-deserve-breathe-survivor-2009-fort-hood-massacre-speaks-after-hearing-shooters-possible-execution/.

Hasan was born in 1970 in Arlington, Virginia, to Palestinian immigrant parents. In 1995, Hasan graduated with honors from Virginia Tech University with a degree in biochemistry. Following graduation, he attended Army Officer Candidate School, and was selected to attend medical school at the Uniformed Services University of Health Sciences in Bethesda, Maryland. Hasan graduated in 2003, later earning a master’s degree in public health.James C. McKinley Jr. and James Dao, “Fort Hood Gunman Gave Signals Before His Rampage,” New York Times, November 8, 2009, www.nytimes.com/2009/11/09/us/09reconstruct.html?pagewanted=all&_r=1.

Hasan’s radicalization is believed to have begun as early as 2000 when, following the death of his parents, Hasan reportedly grew more overtly pious. In 2001, Hasan attended Anwar al-Awlaki’s Dar Al-Hijrah Islamic Center in Virginia, though it is not clear if the two interacted.James C. McKinley Jr. and James Dao, “Fort Hood Gunman Gave Signals Before His Rampage,” New York Times, November 8, 2009, www.nytimes.com/2009/11/09/us/09reconstruct.html?pagewanted=all&_r=1.

In December 2008, Hasan contacted Awlaki through Awlaki’s personal website. Hasan asked Awlaki to “make some general comments about Muslims in the u.s. military [sic],” including Hasan Akbar, the U.S. army sergeant who killed two soldiers in Kuwait in March 2003.Manuel Roig-Franzia, “Army Soldier Is Convicted In Attack on Fellow Troops,” Washington Post, April 22, 2005, http://www.washingtonpost.com/wp-dyn/articles/A7210-2005Apr21.html. Hasan asked whether Awlaki would “consider someone like Hasan Akbar or other soldiers that have committed such acts with the goal of helping Muslims/Islam…fighting Jihad[?],” and “if they did die would you consider them shaheeds[?]”“Anwar Awlaki E-mail Exchange with Fort Hood Shooter Nidal Hasan,” IntelWire, July 19, 2012, http://news.intelwire.com/2012/07/the-following-e-mails-between-maj.html.

The FBI intercepted the message but classified it as “Not a product of interest.”“FINAL REPORT of the WILLIAM H. WEBSTER COMMISSION on The Federal Bureau of Investigation, Counterterrorism Intelligence, and the Events at Fort Hood, Texas, on November 5, 2009,” William H. Webster Commission, Accessed July 2, 2016, 41-52, https://archive.org/details/final-report-of-the-william-h.-webster-commission. Over the next two months, Hasan sent six emails to Awlaki and Awlaki responded to two, after which Hasan continued to email him. Hasan asked several questions about Hamas and the current Israeli-Palestinian conflict, posited an essay scholarship prize for the question “Why is Anwar Al Awlaki a great activist and leader?” and offered to help Awlaki “in accordance with the u.s. Law [sic].”“FINAL REPORT of the WILLIAM H. WEBSTER COMMISSION on The Federal Bureau of Investigation, Counterterrorism Intelligence, and the Events at Fort Hood, Texas, on November 5, 2009,” William H. Webster Commission, Accessed July 2, 2016, 41-52, https://archive.org/details/final-report-of-the-william-h.-webster-commission. In all, Hasan exchanged 16 emails with Anwar al-Awlaki, dated from December 2008 to June 2009.“Anwar Awlaki E-mail Exchange with Fort Hood Shooter Nidal Hasan,” IntelWire, July 19, 2012, http://news.intelwire.com/2012/07/the-following-e-mails-between-maj.html.

In July 2009, Hasan moved to the Fort Hood military post, pending an almost certain deployment to Iraq or Afghanistan.James C. McKinley Jr. and James Dao, “Fort Hood Gunman Gave Signals Before His Rampage,” New York Times, November 8, 2009, www.nytimes.com/2009/11/09/us/09reconstruct.html?pagewanted=all&_r=1. Two weeks after his move, Hasan purchased a Herstal FN Five-Seven handgun from a gun store in Killeen, Texas, allegedly asking clerks for the most technologically advanced weapon available.Jennifer Hlad, “In opening remarks, Hasan says he was ‘on the wrong side’ in US Army uniform,” Stars and Stripes, August 6, 2013, https://archive.org/stream/final-report-of-the-william-h.-webster-commission#page/n0/mode/2up. In October of that year, the U.S. Army notified Hasan he would be deploying to Afghanistan in November.“FINAL REPORT of the WILLIAM H. WEBSTER COMMISSION on The Federal Bureau of Investigation, Counterterrorism Intelligence, and the Events at Fort Hood, Texas, on November 5, 2009,” William H. Webster Commission, Accessed July 2, 2016, 62, https://archive.org/details/final-report-of-the-william-h.-webster-commission.

On November 5, Hasan entered the Soldier Readiness Processing Center at the Fort Hood military post. He told a civilian clerk to leave the room, yelled “Allahu Akbar,” and began shooting. Hasan specifically sought out uniformed soldiers and killed only one individual who was not in uniform.Jennifer Hlad, “In opening remarks, Hasan says he was ‘on the wrong side’ in US Army uniform,” Stars and Stripes, August 6, 2013, https://archive.org/stream/final-report-of-the-william-h.-webster-commission#page/n0/mode/2up. Hasan killed 13 and wounded another 32 before he was subdued by responding police officers.James C. McKinley Jr. and James Dao, “Fort Hood Gunman Gave Signals Before His Rampage,” New York Times, November 8, 2009, www.nytimes.com/2009/11/09/us/09reconstruct.html?pagewanted=all&_r=1.

Hasan was charged with 13 counts of premeditated murder and 32 counts of attempted premediated murder.Michael Muskal and Molly Hennessy-Fiske, “Maj. Nidal Malik Hasan tells court-martial: ‘I am the shooter’,” Los Angeles Times, August 6, 2013, http://articles.latimes.com/2013/aug/06/nation/la-na-nn-nidal-malik-hasan-fort-hood-20130806. In his opening statement at the military tribunal in Fort Hood, Hasan declared himself the shooter and said that he was a member of the “mujhadeen [holy warriors].”Jennifer Hlad, “In opening remarks, Hasan says he was ‘on the wrong side’ in US Army uniform,” Stars and Stripes, August 6, 2013, https://archive.org/stream/final-report-of-the-william-h.-webster-commission#page/n0/mode/2up. Hasan also said that as a member of the U.S. Army, he found himself on the “wrong side,” and had “switched sides.”Josh Rubin and Matt Smith, “‘I am the shooter,’ Nidal Hasan tells Fort Hood court-martial,” CNN, August 6, 2013, www.cnn.com/2013/08/06/justice/hasan-court-martial/. The judge struck down an attempt by Hasan to frame his attack as an effort to protect Taliban fighters in Afghanistan.Michael Muskal and Molly Hennessy-Fiske, “Maj. Nidal Malik Hasan tells court-martial: ‘I am the shooter’,” Los Angeles Times, August 6, 2013, http://articles.latimes.com/2013/aug/06/nation/la-na-nn-nidal-malik-hasan-fort-hood-20130806. Roughly one year after the shooting, Awlaki praised Hasan, stating, “How can we object to...Nidal Hasan’s operation. He killed American soldiers who were on their way to Afghanistan and Iraq. Who would object to that?”Jeremy Havardi, “The children of Anwar Al-Awlaki,” Commentator, May 23, 2013, www.thecommentator.com/article/3605/the_children_of_anwar_al_awlaki.

Statements by Hasan’s acquaintances following the attack reveal that Hasan viewed his military service as deeply in conflict with his religion. According to Duane Reasoner Jr., a friend of Hasan’s who attended mosque, “[Hasan] felt he was supposed to quit [the army]… In the Koran, it says you are not supposed to have alliances with Jews or Christians, and if you are killed in the military fighting against Muslims, you will go to hell.” Reasoner characterized Hasan as “very upset” and stated, “He didn’t want to go to Afghanistan.” In 2004, Hasan reportedly sought legal advice in an effort to terminate his Army contract, which was set to last until 2010. On one occasion in 2009, Hasan asked Osman Danquah—a veteran of the first Gulf War and the cofounder of Killeen mosque which Hasan attended—how he should counsel Muslim soldiers objecting to the wars in Iraq and Afghanistan. Danquah later told the media, “I got the impression he was trying to validate how he was dealing with it.”James C. McKinley Jr. and James Dao, “Fort Hood Gunman Gave Signals Before His Rampage,” New York Times, November 8, 2009, www.nytimes.com/2009/11/09/us/09reconstruct.html?pagewanted=all&_r=1.

Though Hasan did not plead guilty to charges, he refused to field a defense and suggested that an execution would be his martyrdom. In August 2013, the military court found Hasan guilty on all charges and sentenced him to death.Manny Fernandez, “Death Penalty for Rampage at Fort Hood,” New York Times, August 28, 2013, www.nytimes.com/2013/08/29/us/jury-weighs-sentence-for-fort-hood-shooting.html?_r=0. Hasan remains on military death row in Fort Leavenworth, Kansas.“Fort Leavenworth death row inmate Nidal Hasan appears at hearing in Fort Hood massacre case,” Dallas Morning News, January 29, 2015, www.dallasnews.com/news/state/headlines/20150129-fort-leavenworth-death-row-inmate-nidal-hasan-appears-at-hearing-in-fort-hood-massacre-case.ece. Because Hasan received a death sentence, his case qualified for an automatic appeal. However, the commanding general of Fort Hood also had to approve the findings and the sentence before the case could move to the appeal process.“Hasan Faces Lengthy Appeals Process Before Execution,” KUT News, August 29, 2013, https://www.kut.org/texas/2013-08-29/hasan-faces-lengthy-appeals-process-before-execution.

The appeals process progressed slowly. On December 11, 2020, the Army Court of Criminal Appeals upheld Hasan’s conviction. The court rejected an argument by Hasan’s attorney that the trial should have been moved to a different venue because of prejudicial pretrial publicity. The court also rejected a challenge to the impartiality of the jury based on a juror who had a bumper sticker that read “Major League Infidel.”“Capital Case Roundup — Death Penalty Court Decisions the Week of December 7, 2020,” Death Penalty Information Center, December 11, 2020, https://deathpenaltyinfo.org/capital-case-roundup-death-penalty-court-decisions-the-week-of-december-7-2020. On March 28, 2023, Hasan’s defense filed an argument with the Court of Appeals for the Armed Forces. The court initially issued a decision upholding the conviction in September 2023. However, the defense immediately submitted a request for reconsideration. On March 4, 2024, the court reissued its decision to uphold Hasan’s conviction.UNITED STATES Appellee v. Nidal M. HASAN, Major United States Army, Appellant No. 21-0193 Crim. App. No. 20130781, U.S. Court of Appeals for the Armed Forces, March 4, 2024, https://www.armfor.uscourts.gov/opinions/2023OctTerm/210193.pdf; William Cassara, “Court of Appeals for the Armed Forces Affirms Convictions and Death Sentence For Army Major,” William E.

On August 1, 2024, Hasan’s attorney filed a petition for a writ of certiorari with U.S. Army’s Defense Appellate Division in Fort Belvoir, Virginia, to petition the U.S. Supreme Court to hear his appeal. A February 21, 2025, response by the U.S. Department of Justice argued that Hasan’s court-martial conviction on 13 counts of premeditated murder and 32 specifications of attempted premeditated murder had been appropriate. The Department of Justice further noted that the conviction had been affirmed through subsequent appeals in the Army Court of Criminal Appeals and the Court of Appeals for the Armed Forces. On March 31, 2025, the U.S. Supreme Court declined to hear Hasan’s appeal.Emily Hilley-Sierzchula, “U.S. Supreme Court denies petition filed by Nidal Hasan, infamous Fort Hood mass murderer,” KDH News, April 7, 2025, https://kdhnews.com/military/u-s-supreme-court-denies-petition-filed-by-nidal-hasan-infamous-fort-hood-mass-murderer/article_7913088b-71d9-4d52-bc66-381d49240ea4.html.

Barring another appeal, Hasan will face the death penalty upon approval by the White House. At the end of September 2025, U.S. Secretary of War Pete Hegseth issued a statement calling for the death penalty for Hasan. Hegseth said that he was “100 percent committed to ensuring the death penalty is carried out for Nidal Hasan. This savage terrorist deserves the harshest lawful punishment for his 2009 mass shooting at Fort Hood. The victims and survivors deserve justice without delays.”Adam Schindler, “‘He doesn’t deserve to breathe’: Fort Hood massacre survivor speaks after hearing of shooter’s possible execution,” KWTX 10, September 29, 2025, https://www.kwtx.com/2025/09/25/he-doesnt-deserve-breathe-survivor-2009-fort-hood-massacre-speaks-after-hearing-shooters-possible-execution/.
