Attorneys for wrongly deported Kilmar Abrego Garcia pushed back on the Trump administration's invocation of the state secrets privilege in a court filing Monday.

One hundred fifteen children were rescued in the operation, which was executed over the course of five days, the DOJ said in its release.

Tuesday's hearing before a panel of three judges at the U.S. Court of International Trade will be the first major legal test of Trump's tariffs.

Deputy Attorney General Todd Blanche has been appointed to serve as the acting librarian of Congress, a U.S. Justice Department spokesman confirmed on Monday, after President Donald Trump recently fired Carla Hayden.
