Trump: 'No reason' to honor Dems' 'very partisan' subpoenas, as McGahn testimony fight looms

The White House will fight House Democrats' subpoena of testimony and documents from ex-White House counsel Don McGahn, Fox News is told -- and almost immediately, House Judiciary Committee chairman Jerry Nadler, D-N.Y, characterized the move as "one more act of obstruction" by the Trump administration.

The brewing fight over the McGahn subpoena was poised to set up a series of other contentious legal showdowns as Democrats seek to publicly question more current and former Trump aides who featured prominently in Special Counsel Robert Mueller's report on the Russia investigation.

Fox News is also told the White House intends to vigorously oppose subpoenas that might run up against executive privilege, a power sanctioned by the Supreme Court that allows the president and members of the executive branch to shield certain internal communications from disclosure, absent a compelling overriding justification.

In an interview with The Washington Post published Tuesday evening, Trump insisted that no "final, final decision" had been made on whether to assert executive privilege to block aides from testifying, but emphasized that he had already allowed his associates to speak at length with Mueller's team.

“There is no reason to go any further, and especially in Congress where it’s very partisan — obviously very partisan," Trump told The Post. "I don’t want people testifying to a party, because that is what they’re doing if they do this."
