U.S. Marshal St. Pierre was also nominated by the White House last fall with his confirmation passing out of committee in early March by a bipartisan vote of 20 to 2.
Sen. Susan Collins (R) has spoken highly of St. Pierre throughout the confirmation process, praising his more than three decades of law enforcement service and citing his leadership during the 2023 mass shooting in Lewiston.
He served as the Chief of the Lewiston Police Department from 2021 until his retirement from the force last year.
As chief, he oversaw a department of 99 employees and managed a budget exceeding $10 million.
A 2018 graduate of the FBI National Academy in Quantico, Virginia, St. Pierre is a member of the FBI National Academy Associates, the International Association of Chiefs of Police and the Maine Chiefs of Police Association.
