Arkansas Sen. Tom Cotton said Sunday that he has not seen evidence that the Obama administration wiretapped Donald Trump or Trump Tower during the campaign.

"I've seen no evidence of the allegations we've seen in the media. Whether that's a potential application or denial of the application, or a submission of the application or surveillance," Cotton said on "Fox News Sunday." "It doesn't mean that none of these things have happened, just means I haven't seen them yet. I would not want to speculate about media reports based on anonymous sources.


"I would prefer to deal with facts," said the first-term Republican, a member of the Select Committee on Intelligence.

Host Chris Wallace asked Cotton whether the committee will also investigate whether the "Obama administration abused its executive role," an allegation from the Trump administration.

"We are going to review allegations of any kind of improper contacts between Russian officials and campaign officials or other American citizens. I'm sure that we will be reviewing any allegations such as this," Cotton said.

On Saturday morning, President Donald Trump tweeted claims that former President Barack Obama wiretapped phones in Trump Tower. The president provided no evidence, nor did he provide the source of the information.

White House press secretary Sean Spicer released a statement Sunday saying that Trump is requesting that as part of their investigation into Russian activity in the 2016 election, "congressional intelligence committees exercise their oversight authority to determine whether executive branch investigative powers were abused in 2016."
