President Obama doesn’t believe Donald Trump.

Regarding President Obama’s reaction to his successor’s unsubstantiated wiretapping claims a source close to the former president tells NBC News Mr. Obama “rolled his eyes.” This person familiar with the president’s thinking says Mr. Obama believes the claims “undermine the integrity of the office of the president,” but don’t undermine his own integrity, because “he didn’t do it.”

The FBI director doesn’t believe Donald Trump.

FBI Director James Comey was "incredulous" over the weekend after President Donald Trump's allegation via Twitter that former President Barack Obama ordered a wiretap of his phones during the campaign, a person familiar with the matter told CNN.

Trey Gowdy doesn’t believe Donald Trump.

“I don't think the FBI is the Obama team and I don't think the men and women who are career prosecutors at DOJ belong to any team other than a blindfolded woman holding a pair of scales,” Gowdy said.

Not even Sean Spicer believes Donald Trump.

“No, that’s above my pay grade,” said Sean Spicer, the White House press secretary and a feisty Trump loyalist, when asked on Tuesday at an on-camera briefing if he had seen any evidence to back up Mr. Trump’s accusation. The reporters kept at him, but Mr. Spicer pointedly and repeatedly refused to offer personal assurances that the president’s statements were true.

And since Trump insists on bringing Congress into the picture, in hopes that Jason Chaffetz can Benghazi it into a lasting distraction from everything else that’s going on in his White House, he might want to worry that Congress just might not carry his water on this one.
