A federal judge in Washington, D.C., on Tuesday abruptly halted the House’s lawsuit seeking President Donald Trump’s federal tax returns pending an appeals court ruling on whether former White House counsel Don McGahn can be compelled to testify.

U.S. District Judge Trevor McFadden of the District of Columbia at 2:54 p.m. Tuesday scheduled a phone conference in the case for 3 p.m. Shortly afterward, an order was issued saying the case will be stayed until the U.S. Court of Appeals for the D.C. Circuit issues its decision in the McGahn case.
