WATCH: Ted Cruz refuses to say if Trump should be impeached if he colluded with Russians

In a Fox News segment, former presidential candidate and current senator Ted Cruz (R-TX) refused to answer questions about whether or not he believes President Donald Trump should be impeached.

When asked by host Neil Cavuto whether he would consider any proven Russian collusion an "impeachable offense," Cruz deflected.

"Every person who has looked at the classified material has said they see no collusion," Cruz said. 

"I'm taking it to its' extreme," Cavuto said. "If it's proven that there was some collusion, many have argued that that is not an impeachable offense. Do you think it is?"

"Neil, I'm not gonna go down rabbit holes," Cruz rebutted. "If everyone who's look at the evidence says there's no evidence of collusion, at some point Washington starts to get silly where there's an investigation about an investigation."

"We don't have all the evidence, right?" Cavuto concluded.
