Trump just took aim at Arizona Sen. Jeff Flake, blasting him for comments he made about him on Saturday and claiming Flake’s “political career anyway is ‘toast.’”

In a tweet, Donald Trump branded the senator “Jeff Flake(y)” and called him “unelectable.”

“Sen. Jeff Flake(y), who is unelectable in the Great State of Arizona (quit race, anemic polls) was caught (purposely) on “mike” saying bad things about your favorite President. He’ll be a NO on tax cuts because his political career anyway is ‘toast,'” – Donald Trump on Twitter.

On Saturday, a hot mic picked up Flake warning that GOP will be “toast” if it becomes the party of President Trump and GOP Senate candidate Roy Moore.

“If we become the party of Roy Moore and Donald Trump, we are toast,” Flake told his friend Mesa Mayor John Giles according to a sound recording picked up by the a ABC affiliate KNXV microphone.

Flake and president Trump have become repeatedly entangled in public feuds, sparring with one another over their policies.
