House Intelligence Committee Chair Devin Nunes (R-CA) on Tuesday afternoon said that he has not seen any evidence to support President Donald Trump’s unsubstantiated claim over the weekend that President Obama wiretapped Trump Tower.

“I have not seen that evidence,” Nunes told reporters, according to Reuters. “I think the bigger question that needs to be answered is whether or not Mr. Trump or any of his associates were in fact targeted by any of the intelligence agencies or law enforcement authorities.”

He previously said that his committee would look into Trump’s claims after the President called on Congress to do so.

The congressman said that the committee should have been briefed on any such activity.

“We are supposed to be kept up to speed on any pertinent counterintelligence investigation,” Nunes said, per Reuters. “If Trump or any other political campaign, or anybody associated with Trump, was under some type of investigation, that clearly should have risen to the Gang of Eight level.”

Asked if he believes Trump’s claim, Nunes suggested that reporters not take Trump’s comments literally.

“A lot of the things he says, you guys take literally,” he said, according to CNN.

Senate Intelligence Committee Chair Richard Burr (R-NC) also said that he had not seen evidence and suggested that his committee may hold off on probing the matter until evidence presents itself.

“We’re going to go anywhere there is intelligence or facts that send us,” he told CNN. “So I’m not going to limit it one way or the other. But we don’t have anything today that would send us in that direction, but that’s not to say that we might not find something.”
