Republican Arizona Sen. Jeff Flake, known for his libertarian leanings and more recently for his critique of President Donald Trump's behavior, announced today he will not be running for re-election next year.

He will serve out the rest of his term, but he told the Arizona Republic, "there may not be a place for a Republican like me in the current Republican climate or the current Republican Party."

He explained further that he simply could not toe the line with the president's restrictionist attitudes on trade and immigration:

"Here's the bottom line: The path that I would have to travel to get the Republican nomination is a path I'm not willing to take, and that I can't in good conscience take," Flake told The Republic in a telephone interview. "It would require me to believe in positions I don't hold on such issues as trade and immigration and it would require me to condone behavior that I cannot condone."
