Rep. Justin Amash, just days after he announced his departure from the Republican Party, said Sunday he would have left even if Donald Trump weren’t the president but insisted that this term in Congress was what “really broke it for me.”

“Over the years, I’ve seen that people are just falling in line behind the leaders, including people in my own caucus, which I left,” the five-term Michigan lawmaker told host Jake Tapper on CNN’s “State of the Union.” “So it has gotten worse and worse and I think this was the term that really broke it for me.”

Amash said he has been bothered by the way Trump expects Republicans to be first and foremost loyal to him, not the party itself.
