The judiciary panel on Tuesday asked a federal judge to make a ruling quickly on whether McGahn must testify in the House impeachment inquiry, citing a"finite window of time" when he's needed. A quick ruling siding with the House could yield major new impeachment witnesses about the Mueller investigation, Ukraine and obstruction of justice from people who worked in the White House and have thus far refused to testify.
The White House stopped McGahn from testifying last spring, citing"absolute immunity" over its high-level former officials.The question of whether Trump lied to Mueller, the House notes, has become more pressing since his former deputy campaign chairman testified in court last week that Trump expected information after speaking with Stone, who was pursuing details from WikiLeaks in 2016 that could help Trump's campaign.
