Watch: Trump spox schools Martha Raddatz over mainstream media's double standard on anonymous sources

Deputy White House press secretary Sarah Huckabee Sanders tussled with ABC "This Week" host Martha Raddatz on Sunday during a discussion about President Donald Trump's accusation that former President Barack Obama wiretapped Trump Tower last year.

During the interview, Raddatz came out of the gate charging.

"These are extremely serious charges the president is making. Where is he getting his information?" she pressed.

Huckabee Sanders cited reports from mainstream media outlets like the New York Times, the Washington Post and BBC that reported on potential wiretapping and FISA court order requests.

"I think the bigger thing is: lets find out, lets have an investigation," Huckabee Sanders said. "If they're going to investigate Russia ties, lets include this as part of it."

"You guys are always telling us to take the media seriously, well we are today," she added. "If this happened, if this is accurate, this is the biggest overreach and the biggest scandal."

"The president of the United States is accusing the former president of wiretapping him," Raddatz said back, emphasizing her point.

"If this happened—" Huckabee Sanders began to reply.

"IF! IF! IF!" Raddatz interrupted, almost screaming.

The ABC host went on to press Huckabee Sanders over why Trump insisted, as if it was fact, that Obama wiretapped him, while Huckabee Sanders went on to say there needs to be an investigation into the claims.

"I think he's going off of information that he's seen that has led him to believe that this is a very real potential," Huckabee Sanders said. "And if it is, this is the greatest overreach and the greatest abuse of power that I think we've ever seen and a huge attack on democracy itself and the American people have a right to know if this took place."

Raddatz followed up by noting that the reports Huckabee Sanders cite mostly cite anonymous sources themselves, implying they can't be believed.

"I love how anonymous sources don't count when it's something that's positive in this administration and against the former one," Huckabee Sanders shot back. "You guys use anonymous sources every single day."
