President Donald Trump lashed out at Sen. Jeff Flake (R-Ariz.) after he was heard over a hot mic saying the Republican Party would be toast if it stuck with the president and Alabama Senate candidate Roy Moore.

Trump tweeted Sunday that Jeff Flake(y) was unelectable. The president claimed that Flake was caught (purposely) on mike saying bad things about your favorite President. Trump also said he expects Flake to vote against the GOP tax reform package.

Flake, who announced last month that he wont seek re-election , took the hot mic issue in stride, saying no one should be surprised by what he said.

Flake was talking to the mayor of a Phoenix suburb on Friday after a town hall meeting when he said: If we become the party of Roy Moore and Donald Trump , we are toast. The comment was picked up by ABC affiliate KNXN .

No news here, Flake tweeted Saturday after his comments began to attract media attention. Ive been saying this to anyone who will listen.

Flake has not yet responded to the (latest ) attack from Trump. Nor has he discussed how he plans to vote on the tax package.

In an emotional speech on the Senate floor last month, Flake announced his plans to retire. It is time for our complicity and our accommodation of the unacceptable to end, he said.
