Former National Security Advisor HR McMaster said unequivocally that he would not work for the former president Donald Trump again.

McMaster appeared on Monday AC360 on CNN to promote his new book At war with ourselves. He served in the Trump administration from February 2017 to April 2018.

The former NatSec adviser complained that Trump had humiliated the late senator. John McCain’s military service when the former president said McCain was considered a hero only because he was a prisoner of war.

“The president is often very abusive, brash and says things that are completely out of line,” McMaster said. “I’ve recounted many of them in my book. But you know, he’s an extremely disruptive person. I saw it as my job not to constrain him but to help him disrupt what needed to be disrupted.”

Anderson Cooper interrupted to ask McCaster about the idea of ​​serving in a second Trump administration.

“Would you work in a Trump White House again?” asked the moderator.

“No,” he answered without hesitation. “I will work in any department where I feel I can make a difference, but I’m fed up with Donald Trump.”

Cooper then asked if he would serve under the Vice President Kamala Harris if she is elected president.

“I don’t know if I could make a difference there, probably because of my different views and the question of what is a sensible policy for the Middle East or what just fills the gap,” McMaster replied.
