The legal battle over former White House counsel Don McGahn’s congressional testimony will last through at least the end of October, Politico reported, citing a new schedule issued by Judge Ketanji Brown Tuesday.

As part of the House Judiciary Committee’s inquiry into whether to recommend articles of impeachment against President Trump, House Democrats are suing to compel McGahn to cooperate with their subpoena for testimony. The federal judge’s new timetable will put the panel in a bit of a time crunch, given there are only 16 days that Congress is still in session after Oct. 31. House Judiciary Committee Chairman Jerry Nadler (D-NY) has previously said he wants his committee to decide whether to recommend impeachment before the December recess begins.

McGahn was a crucial witness in the obstruction of justice portion of special counsel Robert Mueller’s probe. House Democrats sued after McGahn refused to comply with their subpoena, following President Trump’s directive that he and other top aides have complete immunity from cooperating with congressional subpoenas.

Just last week, House Democrats asked that the consideration of their lawsuit be expedited.
