Gregory Bovino, who became a face of the Trump administration’s aggressive immigration enforcement tactics in large cities, says he plans to retire from the U.S. Border Patrol in the coming weeks. Bovino joined the Border Patrol in 1996 and steadily rose through the ranks but wasn’t well-known outside the agency until last June, when he took command of a crackdown in Los Angeles. Bovino was a near-daily presence as Minnesota’s Twin Cities turned into a battleground between demonstrators and immigration authorities in January that led to the deaths of U.S. citizens Renee Good and Alex Pretti.
