Republican Senator Jeff Flake donated $100 to the opponent of scandal-plagued Roy Moore.

Flake addressed the check to “Doug Jones for US Senate” — the Democratic candidate running against Moore for the Alabama Senate seat.

“Country over Party,” Flake wrote on Twitter along with an image of the check.

The donation came one day after President Trump offered his “full support” to Moore — who is accused of molesting teenage girls.

Flake called Trump’s endorsement a “big mistake” — adding that “A Roy Moore victory is no victory for the GOP and the nation.”
