Sen. Mark Warner, D-Va., told more than 100 people at a Democratic Senatorial Campaign Committee event that they should "buckle up" for more revelations in the Russia investigation in the coming months, boastfully joking that there was information only known to himself and and special counsel Robert Mueller.

“If you get me one more glass of wine, I’ll tell you stuff only Bob Mueller and I know," Warner quipped to the crowd, according to Politico, referring to Mueller's probe into Russian meddling in the 2016 election and whether President Trump obstructed justice.

"If you think you’ve seen wild stuff so far, buckle up. It’s going to be a wild couple of months," Warner added.

Any Mueller bombshells released close to this November's midterm elections are sure to amplify attacks by Republicans led by Trump that the probe has been politically motivated.

Warner, the top Democrat on the Senate Intelligence Committee, made the comments at the DSCC’S annual Majority Trust retreat on Martha’s Vineyard, Mass., on Friday.

In the past, Warner has lambasted allies of President Trump for knowingly leaking classified information to help the president.

"The first thing you learn when you get involved with the intelligence community is you have to protect sources and methods. People's lives depend upon it," Warner said during an interview on CNN's "State of the Union" in May.
