June 27 (UPI) -- President Donald Trump on Saturday announced that he nominated former Oklahoma state trooper Lance Schroyer to be director of Immigration and Customs Enforcement.

Schroyer, a senior advisor at the Department of Homeland Security and retired U.S. Marine, will replace former acting ICE Director Todd Lyons, who announced in April that he would leave the agency on May 31.

Trump announced that he is nominating Schroyer for the position in a post on Truth Social, touting his 29 years in law enforcement, including in previous partnership roles with ICE.

"He is a PATRIOT with real operational experience, and proven leader with DECADES of experience locking up the worst of the worst," Trump said in the post.
