Happening Now: White House Holds Briefing Amid Trump, Supreme Court Immigration Scuffle

White House press secretary Karoline Leavitt will brief reporters Tuesday afternoon as President Trump and the Supreme Court tango over his sweeping immigration agenda — including using the 1798 Alien Enemies Act to speed up deportations.

The nation's highest court moved early Saturday to halt the administration's ability to use the 18th century law to fly migrants to El Salvador.

Trump on Monday complained that he's been “stymied at every turn” by the courts, arguing the administration can’t hold trials for migrants it plans to deport amid accusations they are gang members. Democrats and other critics have admonished the administration for sidestepping "due process."

The briefing also comes as Kilmar Abrego Garcia, a man who was mistakenly deported to El Salvador in mid-March, remains in the nation's most notorious prison. The administration's refusal to facilitate his return, which the Supreme Court ruled they must do earlier this month, has sparked criticism over whether the president is purposely defying court orders.

The event is scheduled to begin at 1 p.m. EDT.
