Story highlights "I mean, this becomes more and more bizarre. In fact, you can't make it up," McCain said

McCain said he believes Russian President Vladimir Putin poses a bigger threat to national security than ISIS

Washington (CNN) Arizona Sen. John McCain is not pleased about reports that Jared Kushner proposed setting up a secret communications channel between the Trump transition team and the Kremlin.

"I don't like it," the Republican lawmaker said Monday in an interview with the Australian Broadcasting Corporation's "7:30" when asked about President Donald Trump's son-in-law's possible ties to Russia.

"I know that some administration officials are saying 'well, that's standard procedure.' I don't think it's standard procedure prior to the inauguration of the president of the United States by someone who is not in an appointed position. And I think that (former FBI Director James) Comey we now know took action that he did in regards to then-candidate (Hillary) Clinton because of some false news that was being put out by the Russians. I mean, this becomes more and more bizarre. In fact, you can't make it up."

McCain's comments come two days after news broke that Kushner, a trusted aide to President Donald Trump and husband to Ivanka Trump, chatted with Russia's ambassador to the US Sergey Kislyak at Trump Tower in December about the proposed channel. A source told CNN the channel was meant to discuss military operations in Syria and other matters.

The chairman of the Senate Armed Services Committee also said he believes Russian President Vladimir Putin poses a bigger threat to national security than ISIS.
