White House press secretary Sean Spicer said Tuesday that senior Trump aide Kellyanne Conway's remark that microwaves can be used to conduct surveillance was made “in jest.”

“I think there’s pretty sound evidence that the microwave is not a sound way of surveilling someone," Spicer told reporters during the daily briefing.

"I think that has been cleaned up. It was made in a jest. So I think we can put that to rest,” he added of the comment, while maintaining that the president believes that surveillance was conducted during the 2016 election.

The question came following an interview published in a New Jersey newspaper in which Conway mentioned “microwaves that turn into cameras” when discussing surveillance methods.

“What I can say is there are many ways to surveil each other,” Conway told the New Jersey’s Bergen County Record. “You can surveil someone through their phones, certainly through their television sets — any number of ways.”

The remark prompted mockery on late-show programming and President Obama's former White House photographer poked at it.

Without offering evidence, Trump earlier this month accused Obama of wiretapping Trump Tower before the November presidential election. A spokesman for Obama denied he or any White House official ordered surveillance.

The Department of Justice has asked the House Intelligence Committee for additional time to comply with the committee’s request to produce evidence of any surveillance.
