After the articles of impeachment are drawn up they are looked over by the Judiciary committee. They take recommendations from several other groups for the formation of the final document. The articles are voted on by the committee before they pass on to the house floor.
Democrats hold a heavy majority on the committee currently meaning that if the articles were drawn they would surely get out of committee.
