Robert Mueller's Russia probe has become "an intergalactic disgrace," Dan Bongino said, arguing no wrongdoings by President Trump have been found even after White House Counsel Don McGahn willingly spoke with members of the special counsel's team.

President Trump tweeted on Saturday that he allowed McGahn and other members of his staff to "fully cooperate" with Mueller.

I allowed White House Counsel Don McGahn, and all other requested members of the White House Staff, to fully cooperate with the Special Counsel. In addition we readily gave over one million pages of documents. Most transparent in history. No Collusion, No Obstruction. Witch Hunt! — Donald J. Trump (@realDonaldTrump) August 18, 2018

The New York Times report also revealed that McGahn spoke with the team for more than 30 hours over the last nine months, and that "he never saw Mr. Trump go beyond his legal authorities."

"This case has gone from embarrassing to really like an intergalactic disgrace at this point," Bongino said Monday on "Fox & Friends."

Bongino added that Mueller knows that his investigation into alleged Russian meddling in the 2016 election "is a joke."

Trump's attorney, Rudy Giuliani, said Sunday in an NBC interview that Mueller is "down to desperation time" in his investigation.

"They have to write a report, and they don't have a single bit of evidence," he said.

The Failing New York Times wrote a story that made it seem like the White House Councel had TURNED on the President, when in fact it is just the opposite - & the two Fake reporters knew this.

The Times report also notes that McGahn was "stunned" that Trump allowed him to speak with Mueller.

Bongino said that if Trump is actually guilty of collusion or obstruction of justice, "he's the worst guilty person" he's ever seen.

"You don't waive privilege ... if you're guilty," he said. "The left can't get out of their own way. They can't see the fact that Trump may be open on this entire thing because he did nothing wrong."
