Following his dramatic retirement speech on the Senate floor yesterday, Sen. Jeff Flake (R-Ariz.) said on “Good Morning America” that more senators will follow in making their true feelings about President Trump known even if they share a party label with him.

“A lot of my colleagues have spoken out and I think a lot more will,” Flake said.

Flake argued that his colleagues must also “speak out against the tweeting and the behavior that just isn’t becoming and is beneath the office of the president.”

Flake also didn’t rule out challenging Trump in 2020 for the Republican nomination. “You know, that’s a long time away. And we’ll deal with that when it comes to it,” he said.
