Sen. John Cornyn, the No. 2 Senate Republican, made it clear that he believes the intelligence community and special counsel Robert Mueller's indictments.

Cornyn says Trump seems concerned his election is being delegitimized by critics.

“I don’t think we should be taking a former KGB colonel’s word for what their intelligence apparatus is doing or not doing. I believe our intelligence community, and their assessment, and I think what special counsel Bob Mueller just indicted — the 12 GRU officials — is spot on. So I don’t know what the President is trying to use some sort of carrot-and-stick approach with Putin, but I believe the intelligence community.”

Asked why he thinks President Trump has trouble believing the intelligence community, is it because he thinks it undermines his election, here's what Cornyn said:

“I think there is some element of that. He takes it all very personally like this is an attempt by Hillary supporters to delegitimize his election. But everyone agrees it didn’t change the outcome, and, to me, I think that is a critical point.”
