U.S. President Donald Trump was sued on Friday by the Democratic Party over a recent executive order it says violates federal election law by giving him too much power over the independent Federal Election Commission.

National Democrats sued Friday to stave off what they say could be President Donald Trump’s destruction of impartial campaign finance regulation by the Federal Election Commission. The Democratic National Committee and the campaign arms for congressional Democrats say Trump’s executive order taking control of all independent agencies in the Executive Branch means the FEC could now be weaponized against Trump’s political adversaries in ways it was designed to prevent in the aftermath of Watergate.
