James Clapper doesn't know if there was collusion between Trump and Russia

"I don't know if there was collusion or not," Clapper said.

"I don't know if there was collusion or not," Clapper said during an interview Friday with MSNBC. "I don't know if there was evidence of collusion or not, nor should I have."

"When James Clapper himself, and virtually everyone else with knowledge of the witch hunt, says there is no collusion, when does it end?" he tweeted.

"It’s not surprising or abnormal that I would not have known about the investigation, or more importantly the content of that investigation," Clapper said.

Trump tweeted at the time:

In March, Clapper told ABC News' Brian Ross that he had not seen any evidence of potential collusion through the time he left office on Jan. 20.

"There was no evidence whatsoever, at the time, of collusion between the Trump campaign and the Russians," said Clapper.

Later that month, Trump tweeted about the matter.
