Former CIA Director John Brennan said special counsel Robert Mueller’s public message Wednesday will escalate calls for impeaching President Trump.

“I think Bob Mueller’s public statement today is going to give momentum to those who want to move forward with impeachment hearings,” Brennan said on MSNBC. “I think there can be no doubt about Mr. Mueller’s message that the obstruction of justice issue is not resolved, and that there needs to be follow-up action on it.”
