In an interview with the Bergen County Record published Sunday, Conway had said that people should think beyond wiretapping in terms of monitoring individuals, saying "there are many ways to surveil each other".
"What I can say is there are many ways to surveil each other now, unfortunately ... Microwaves that turn into cameras", adding: "We know this is a fact of modern life".
The Trump administration is under mounting pressure to provide proof to shore up Mr Trump's unsubstantiated allegation that Mr Barack Obama ordered the phones to be tapped at Trump Tower during the election campaign.
Mr Spicer said there have been "numerous reports from a variety of outlets over the last couple months that seemed to indicate that different types of surveillance occurred during the 2016 election".
However, Conway lauded the committee for agreeing to look into Trump's claims that he was wiretapped.
Of course, if Trump's claims were true, it would certainly be a new low-but with no evidence to back up this accusation, Trump is actually the one in the wrong.
"And when Inspector Gadget heard that, he said, 'Even I think you're insane and my hat turns into a helicopter, ' " Meyers quipped.
"A cardinal rule of the Obama administration was that no White House official ever interfered with any independent investigation led by the Department of Justice", Obama spokesman Kevin Lewis said, in a statement following the allegations.
Conway later clarified that her remarks about the president and wiretapping were intended only as general comments about surveillance. "I wasn't making a suggestion about Trump Tower". "I was reflecting what people saw in the news last week, which were several articles about how we can surveil each other generally".
Conway alleged in the interview that surveillance of the Trump campaign went beyond wiretapping, though she did not offer any evidence to back up her claim.
Investigators better get over and inspect the microwaves at Trump Tower quickly.
