Former Maryland Gov. Martin O'Malley says the country is experiencing a "constitutional crisis" as the controversy of Russia's meddling in the 2016 election swirls around President Donald Trump.

"We're going through a constitutional crisis, gentlemen, and we'll see how strong our institutions are and the rule of law are in the United States of America," O'Malley told CBS News Chief White House Correspondent Major Garrett and Political Director Steve Chaggaris on this week's episode of "The Takeout" podcast.

"I think that what we see here is a case with some pretty compelling circumstantial evidence and it abounds," he added. "Everyone agrees that the Russians were involved in this. The question is: what did Donald Trump know and when did he know it and what did members of his campaign know?"

The former Democratic presidential candidate is convinced he knows the answer to those questions.

"I have no doubt that in the fullness of time, it will be revealed that Donald Trump, in fact, and his campaign were very much aware of what the Russians were doing."
