A three-judge panel on the U.S. Court of Appeals for the D.C. Circuit on Tuesday wrestled over whether individual members of the House Oversight Committee can go to court to gain access to documents on President Donald Trump’s D.C. hotel.

Circuit Judges David Tatel, Patricia Millett and Senior Judge Douglas Ginsburg questioned whether the court should be involved in a dispute between the executive and legislative branches in the first place. But the panel also pressed a Justice Department attorney on what circumstances federal agencies should be compelled to provide such information to individual lawmakers.
