Sen. John McCain Thursday called for a select committee to be formed to clear up whether there was coordination between President Donald Trump's 2016 campaign and Russian influences, while saying he finds comments made by House Intelligence Committee Devin Nunes about information gathered through intelligence gathering "very disturbing."
"I have not seen anything like that," McCain told NBC's "Today" show about Nunes' comments to reporters that Trump "to some degree is right" about being placed under surveillance by former President Barack Obama's administration.
"I'm happy to say in the Senate Intelligence Committee there's a good working relationship between Sen. [Richard] Burr and Sen. [Mark] Warner."
Nunes had also told Trump about the findings, drawing criticism from Rep. Adam Schiff, the top Democrat on the Intelligence Committee, who said Nunes will need to decide if he'll chair an independent investigation or be a White House surrogate, as he can't be both.
McCain, though, said he can't make the decision about whether Nunes' comments mean the House Intelligence Committee should shut down its investigation.
"It's up to the House of Representatives," said McCain. "I can say that there's so many moving parts here, including the latest news this morning, that supposedly, there was coordination between the Trump campaign and the Russians, for which I've seen no substantiation. But it continues on and on."
And that, said McCain, is why he's calling for a select committee to clear up the issues involving Russia and Trump's claims that President Barack Obama had his offices at Trump Tower wiretapped.
Nunes on Wednesday said that Trump and his associates were caught up in "incidental collection" of data, and Trump has said he felt somewhat vindicated by the information he received, but McCain said he does not think anything has changed.
"The president, obviously, can express his views and emotions," said McCain. "But nothing has changed since the director of the FBI [James Comey] said that there was no evidence that Trump Towers had been wiretapped."
McCain also said he believes that there will be additional, damaging information to come out before the investigation into Russia and the Trump campaign concludes.
Schiff, meanwhile, told NBC's Chuck Todd Wednesday that there is "more than circumstantial evidence" that there was collusion between Trump's associates and Russians, but McCain said he himself is "not aware" of such evidence.
"I do know, for example, in the Republican convention, there was to be included a provision that called for the provision of defensive lethal weapons to Ukraine," said McCain. "Somehow that disappeared. I'm curious how that happened."
McCain also discussed the upcoming House vote on the American Health Care Act, and said he does not know if the measure will pass.
"I know there's questions from members from states like mine, that expanded Medicaid, from the bill as I've seen it, and they say there's changes taking place all the time that would have significant impact on my state of Arizona," said McCain.
"I don't know how it will turn out. But I do know this, Obamacare, as it is, is imploding, and it's not working in Arizona, where premiums are going up over 100 percent, so, we've got to do something."
The bill will also likely see changes if it passes through to the Senate, said McCain.
