Chief Justice of the U.S. District Court for the District of Columbia James Boasberg is caught in President Donald Trump’s crosshairs after ordering a two-week halt on deportation flights of Tren de Aragua gang members.

Boasberg is also well-known among Trump allies for his role as a judge on the secretive Foreign Intelligence Surveillance Court during the period when the FBI was investigating whether Trump's successful 2016 campaign had colluded with Russia to tip the outcome of the election.

A federal judge still has questions about the Trump administration’s compliance with his orders, and the administration is still trying not to answer them.
