Former CIA director John Brennan has done his first on-camera interview since Donald Trump revoked his security clearance. Brennan spoke with MSNBC’s Rachel Maddow. During the lengthy interview, he said he stood by his claim that Trump has been treasonous and asks when are Republicans finally going to stand up against him.

His own words speak volumes here:

“I wish I didn’t have to say these things. And it’s one thing to have policy differences or substantive differences with presidents and I’ve had them in the past with previous Presidents. What really gets under my skin is Mr. Trump’s lack of decency, integrity, honesty and his lack of commitment to this country’s well being and national security.

Mr. Trump is motivated by whatever is in the best interest of Mr. Trump. That has been his modus operandi for many decades. I was hoping that he was going to change once he assumed the solemn responsibilities of the office of the presidency. That’s why for my first year I sometimes spoke out when he was in front of the agency’s memorial wall and spoke about the size of his inauguration crowd, but I did it very, very selectively. I gave him a year. I said maybe he is going to adapt and change. But it seemed like day after day, week after week, month after month, things just got worse.

He did not live up to what I think Americans expect of the president of the United States. To speak with great forcefulness but to do it with integrity and honesty. Mr. Trump, time after time, I think has really just disappointed millions of Americans.”
