SPRINGFIELD, Ill. — Gregory M. Gilmore, a federal prosecutor who has worked in the Central District of Illinois since 1994, was sworn in as the district’s 33rd U.S. Attorney at the federal courthouse here, capping a confirmation process that began when President Donald J. Trump nominated him on Jan. 13.
U.S. Magistrate Judge Douglas J. Quivey administered the oath. The United States Senate confirmed Gilmore on May 18, and President Trump signed his commission on May 27.
“As a longtime federal prosecutor, it is my honor to serve as the United States Attorney for the Central District of Illinois,” Gilmore said. “Our Office’s mission is to do justice, ensure community safety, and safeguard the rights of victims. I consider myself fortunate to lead excellent attorneys and support staff across our District as we work with our law enforcement partners to achieve these goals, and I know I have benefited from observing and learning from those who led the Office before me.”
Gilmore brings more than three decades of experience inside the office he now leads. He served as First Assistant U.S. Attorney from 2021 to 2025, Criminal Chief from 2018 to 2021, Civil Chief from 2013 to 2015, and Criminal Supervisor of the Springfield Division from 2007 to 2010. As an Assistant U.S. Attorney, he tried over 25 cases to jury verdict.
Before attending law school, Gilmore worked as a Certified Public Accountant at a big four accounting firm and for the Federal Bureau of Investigation. He later clerked for a state appellate court judge. Gilmore obtained both his law degree and undergraduate degree from DePaul University, where he was a member of the Law Review.
“The Central District of Illinois is a wonderful place to live and work; we will always work to improve to better serve our fellow citizens,” Gilmore said. He has lived in Central Illinois with his wife, Kelly, for more than thirty years, where they raised their three children.
The first U.S. Attorney for the Central District of Illinois was William J. Allen in 1855, who served in what was then known as the Southern District prior to reorganizations within Illinois. Gilmore now assumes leadership of the office as the Trump administration continues filling U.S. Attorney posts across the country.
