Biden appoints new Border Patrol chief amidst immigration policy scrutiny.

President Biden has appointed Jason Owens, who has served in the Border Patrol for over 20 years, as the new Border Patrol chief, succeeding Raul Ortiz. Owens takes over at a time when illegal crossings have decreased, but officials expect the number of crossings to rise again this summer. The Biden administration's border policies are facing legal challenges, which may undermine its efforts to deal with border crossings. The Border Patrol union, which represents largely pro-Republican rank-and-file agents, is a strong supporter of former President Donald J. Trump and has assailed the Biden administration for ending some of Mr. Trump’s border policies.
