President Trump will have the opportunity to be present and defend himself at his trial in the Senate, should things come to that. There is nothing irregular or improper about a "closed-door, " impeachment inquiry. Congress is simply conducting their business as they are required to do and have always done. All the information gathered, along with any potential evidence of any crimes, will be brought before the entire for review house if a motion of impeachment is made. As I have stated before, representatives need to start putting their loyalties to this nation, above their loyalty to their political party.
