A federal trial judge in Washington and former Big Law partner who served as an unpaid volunteer on President Donald Trump’s presidential transition team will oversee the U.S. House lawsuit that seeks to force the Treasury Department and IRS to disclose several years of the president’s tax returns.

The judge, Trevor McFadden, who joined the bench from the Justice Department in 2017, was randomly assigned the case Wednesday. The House filed suit this week, arguing the Trump administration is violating federal law by refusing to turn over Trump’s tax returns to the House Ways and Means Committee.
