They have no ability to bring a criminal case against anyone without the cooperation of the executive branch, which Trump controls. Citizens could file civil lawsuits against the federal government to get injunctions against him. But even then I believe the only repercussion for him not following those injunctions would be Congress impeaching him. Basically, in order to get charged with a crime the executive branch has to do it. Since the president is the head executive, there has to be a special case for him/her: Congress can bring charges I.e. impeachment proceedings.
