U.S. Attorney Leigha Simonton to Leave Justice Department

United States Attorney Leigha Simonton will resign from the Department of Justice effective Jan. 19, the office announced today.  

“I began my career in this office as a summer intern after my first year of law school,” said Ms. Simonton.  “It was love at first sight.  Every day after that internship, I was figuring out how to become an Assistant U.S. Attorney here.  I got that chance when I was nine months pregnant with my first child—a baby who is now 20 years old.  I am so proud to have served as an Assistant U.S. Attorney for almost eighteen years and then to have been chosen to lead this district—comprised of 100 counties and over 8 million people—as the United States Attorney.  I cannot put into words what this experience has meant to me, and I leave with two decades of incredible memories.  There is nothing more important than the work of our outstanding women and men in this office and in North Texas law enforcement, and I will be forever grateful to have been a part of it.”

Nominated by President Joseph R. Biden on Nov. 14, 2022 and unanimously confirmed by the U.S. Senate on Dec. 6, 2022, Ms. Simonton was sworn in as United States Attorney for the Northern District of Texas on Dec. 10, 2022. (Download a high-res version of her headshot here.)

Under her leadership, the district has fought relentlessly for justice, trying its highest number of cases in over a decade. Ms. Simonton actively supervised several high-profile jury trials, from Dr. Raynaldo Ortiz, the anesthesiologist convicted of injecting heart-stopping drugs into patient IV bags, to Christopher Kirchner, the Slync founder found guilty of defrauding investors out of more than $25 million, to Holly Elkins, the woman convicted of helping her fiancé cyberstalk and ultimately murder his former girlfriend and mother of his child.  She also oversaw the charging of a Russian national for using the BitPaymer ransomware variant to attack numerous victims throughout the United States and the sentencing of a Ukrainian national for demanding over $700 million in ransom payments using the REvil ransomware variant.  Other notable cases included charges against 14 individuals in the largest case investigated by the Pandemic Response Accountability Committee Fraud Task Force to date for allegedly bilking the Paycheck Protection Program and numerous financial institutions out of more than $53 million, charges against a Texas Christian University divinity professor for possessing child pornography, the sentencing of a retired Cook Children’s Hospital Chaplain for producing child pornography, the sentencing of a would-be bomber who idolized the Columbine High school shooters, and the sentencing of another man who set off a bomb in his backyard and plotted to blow up a high school.

During her tenure, Ms. Simonton also oversaw the prosecution of 11 drug traffickers charged in the wake of the juvenile fentanyl overdose scandal, which claimed the lives of four Carrollton-area middle and high schoolers and injured 10 more.  In the wake of these tragedies, Ms. Simonton launched the “Protect Our Children Project,” aimed at bringing federal resources to bear on issues affecting schools, including fentanyl use.  She hosted a series of webinars for hundreds of North Texas school administrators that covered the dangers of fentanyl, how to respond to an overdose, and how to discourage teens from using the drug.  She also visited several area colleges to share the dangers of fentanyl with young adults.  And, last summer, along with the other Texas U.S. Attorneys, she met in Austin with the heads of all Texas regional education service centers to provide important information and resources on fentanyl that they could use in Texas public schools.

Ms. Simonton also focused on curbing violent crime in North Texas, and the violent crime rate fell in major North Texas cities during that time. She prioritized prosecution of violent recidivists and launched Operation Take Aim in the summer of 2023 to further target such offenders.  And she partnered with the other Texas U.S. Attorneys and the ATF in the summer of 2024 to launch “Operation Texas Kill Switch,” a statewide initiative to combat the illegal use of machine gun conversion devices, also known as "switches.”  The operation, which included a partnership with CrimeStoppers, raised public awareness of the dangers of switches, generated multiple tips, and resulted in numerous ongoing prosecutions.

The Civil and Appellate Divisions also thrived under Ms. Simonton’s stewardship. Ms. Simonton oversaw the creation and implementation of the district’s new Voluntary Self-Disclosure policy, incentivizing companies to quickly detect, disclose, and remediate suspected misconduct, and negotiated settlements in several self-disclosure cases.  For instance, the Civil Division negotiated a $14.2 million settlement with Horizon Medical Center of Denton for potential violations of Medicare regulations and the physician self-referral law and an $18.4 million settlement with Consolidated Nuclear Security LLC (CNS) after CNS self-disclosed that it submitted false claims for payment to the National Nuclear Security Administration related to the Pantex Plant—the nation’s primary facility for the assembly, disassembly, and retrofitting of nuclear weapons.  Further, the Civil Division negotiated a $4.5 million settlement with a 3D printing company that allegedly transmitted technical data to China in violation of export control laws and obtained $1.2 million in judgments against two doctors who prescribed hydrocodone to drug-seekers without legitimate medical purpose.

Meanwhile, under her leadership, the Appellate Division persuaded the Fifth Circuit to affirm the life sentence of a Michigan man who stalked, transported, and sexually assaulted a 14-year-old girl, convinced the Fifth Circuit that a retrial in the Ruel Hamilton real estate bribery case would not violate double jeopardy, and successfully defended against 19 issues on appeal arising from the Forest Park Medical Center kickback case.  The Appellate Division also successfully defended the conviction of four UDF executives who misled investors and the SEC about their investment fund’s performance; the Fifth Circuit upheld the conviction, citing the government’s “avalanche of evidence” proving its case, and the Supreme Court later denied cert, allowing the Fifth Circuit decision to stand.  

Ms. Simonton also oversaw the progress of the U.S. v. Rahimi case—charged in the Northern District of Texas—through the Fifth Circuit to the U.S. Supreme Court.  She supported the Solicitor General’s efforts seeking certiorari of the Fifth Circuit’s decision invalidating Rahimi’s conviction for using a firearm while under a domestic violence protection order. After the Supreme Court granted cert, she attended the oral argument as a guest of the Solicitor General, and the Supreme Court later decided 8-1 that Rahimi’s statute of conviction was constitutional under the Second Amendment. The Rahimi case originated from the Northern District of Texas’s Domestic Violence Initiative, which targets domestic abusers for federal prosecution and resulted, during Ms. Simonton’s tenure, in cases such as the sentencing of a San Diego man to life in prison for traveling to Texas and killing his boyfriend, and the sentencing of a felon domestic abuser to 10 years in prison for violating his supervised release by attacking his partner.  As U.S. Attorney, Ms. Simonton has been an outspoken advocate for domestic violence awareness, partnering with regional and national domestic violence organizations, holding press conferences with the other Texas U.S. Attorneys to honor Texas domestic violence victims, and sharing resources with other U.S. Attorney’s Offices so they can create their own domestic abuser prosecution programs.

Throughout her time in office, Ms. Simonton and her staff actively supported other especially vulnerable communities, including religious communities.  She held hate-crime seminars for Jewish and Muslim community leaders and oversaw hate-crimes prosecutions that resulted in the sentencing of a Dallas man to 37 years after he shot five individuals, killing one, at a tire shop because it was a Muslim-owned business, and the sentencing of an Amarillo man for threatening to execute three Jewish rabbis.

Ms. Simonton further attempted to stem the tide of defendants who make their way into the federal system, revitalizing and expanding the district’s Project Safe Neighborhood Re-Entry Night program, which educates individuals on state parole and probation about avoiding behaviors, like drug trafficking and gun possession, that could end up in federal prosecution, and connects them with community resources—like therapy, addiction, and job placement programs—to live productive lives.  During her tenure, thousands of such individuals across the district attended these programs, and the vast majority have not reoffended.  Further, Ms. Simonton and her staff created events to foster positive relationships between residents of high-crime communities and the law enforcement officers who serve them, such as adopting neighborhood schools, holding book fairs staffed by U.S. Attorney’s Office personnel and law enforcement officers, and having officers read books to preschoolers via the office’s “Pre-K Reading Program.”

After a brief hiatus, Ms. Simonton anticipates likely reentering private practice, and she plans to continue to advocate for domestic-violence victims and to protect children and young adults from the harms of fentanyl and other threats to their health and safety.  An Acting U.S. Attorney will be announced at a later date.
