"Did the president lie? Was the president not truthful in his responses to the Mueller investigation?" House Director Douglas Letter told the U.S. District Court of Appeals for the District of Columbia Circuit why the house now needs access to grand jury material that Mueller collected in his investigation.
The House's arguments Monday put new focus on whether Trump had lied to Mueller after public disclosures at Roger Stone's trial this month.
Former Trump Vice President of Campaign Rick Gates testified that Trump and Stone talked about information that came in to help the campaign in mid-2016, at a time when Stone was trying to get secret details about stolen Democratic documents that WikiLeaks had.
Former Trump campaign chairman Paul Manafort also apparently told the Mueller grand jury what Trump's approach to WikiLeaks had been in 2016, according to the Mueller report.
But Trump told Mueller in his written statements that he did not remember discussing WikiLeaks with Stone.
The house previously reviewed most of what Mueller had written in his final report, including parts from the public. But the House has not been able to see what Manafort told the jury, which Mueller apparently described in his report. The Mueller report edits details of the grand jury related to a sentence describing Manafort speaking to Trump after WikiLeak's first release, in July 2016.
