House Judiciary Committee chair Jerry NadlerJerrold (Jerry) Lewis NadlerDemocrats are running out of stunts to pull from impeachment playbook Trump asks if Nadler will look into Clinton's 'deleted and acid washed' emails Trump tweets conservative commentator's criticism of FBI director MORE (D-N.Y.) said Sunday that Democrats would call former White House counsel Don McGahn to testify about his testimony for special counsel Robert MuellerRobert (Bob) Swan MuellerSasse: US should applaud choice of Mueller to lead Russia probe MORE's investigation. 

Nadler made the announcement on NBC's "Meet The Press" while saying that Congress needed to hear from people such as Mueller and Attorney General William BarrWilliam Pelham BarrClash with Trump marks latest break with GOP leaders for Justin Amash Schiff: Impeachment proceedings could be 'tool' to get information, evidence Trump fires back at 'loser' GOP lawmaker who said he'd engaged in 'impeachable conduct' MORE

"We have to hear from other people like Don McGahn, who we’re going to call," Nadler added. 

The Democratic lawmaker, a frequent critic of President TrumpDonald John TrumpTrump: 'I will not let Iran have nuclear weapons' Rocket attack hits Baghdad's Green Zone amid escalating tensions: reports Buttigieg on Trump tweets: 'I don't care' MORE's, argued on Sunday that Barr had "clearly misled the American people" on Mueller's investigation into obstruction of justice. 

Among other things, Nadler said that Trump's possible obstruction, "if proven, would be impeachable."

The comments come just days after the Justice Department released a redacted version of Mueller's report into Russian interference and Trump. The report stated that the special counsel was unable to “conclusively determine” that no criminal conduct occurred in regards to obstruction of justice.

It also included several instances of possible obstruction of justice, including Trump's alleged request of McGahn to fire Mueller. McGahn refused to follow through on the request, according to Mueller's report, saying "that he would resign rather than trigger what he regarded as a potential Saturday Night Massacre."

Trump's attorney, Rudy Giuliani, said Sunday that Trump would not have committed obstruction of justice if he fired Mueller because "there were very good reasons to fire" him. 

“Mueller hired a staff in which he had people that I would find very, very questionable as people that should be investigating Donald Trump," Giuliani said.
