A Republican member of the Arizona state legislature took more than $6,000 from the Trump campaign in December, as he was pushing fellow state lawmakers to overturn the November election results, the Arizona Republic reported Saturday.

Accountable.Us, a Washington, D.C.-based progressive advocacy group, told the Republic in a statement that the payment should be explained to understand “how it influenced his official work as a legislator to try and overturn a free and fair election.”
