While Barack Obama has remained largely silent since Donald Trump took office, his official photographer is taking aim at the new administration.

Pete Souza took to Instagram to ridicule the Republican leader’s senior aide Kellyanne Conway after she suggested Mr Obama could have monitored his successor through a microwave.

The photographer posted a picture of the former president holding a camera inside a microwave, accompanied by the caption: “Someone has been photoshopping one of my photos. For the record, it wasn't me.”

Ms Conway made the claims in response to Mr Trump’s explosive and entirely unsubstantiated allegations that Mr Obama wiretapped his office.

“What I can say is there are many ways to surveil each other,” she said in a USA Today interview.

“You can surveil someone through their phones, certainly through their television sets — any number of different ways.”

She went on to claim surveillance could take place with "microwaves that turn into cameras," adding, “We know this is a fact of modern life.”

However, the White House has since claimed Mr Trump did not believe he had been wiretapped “personally” – even as it called on Congress to press ahead with a probe into the allegation.

White House press secretary Sean Spicer insisted Mr Trump still believed the allegation he had made. Yet he said the President had used the word “wiretap” to more broadly refer to surveillance or other activities.

“He does not think Obama went out there and wiretapped him personally,” he said. “There are are a whole host of techniques to or surveil someone,” he said.
