Trump runs the Executive Branch, and the Legislative Branch doesn't have the authority to subpoena his advisors; at least that's what the Supreme Court has said. The lack of civics knowledge in this country is appalling.
After over 4 years of constant surveillance by our biased Injustice Department the idea that President Trump is covering anything up is totally ridiculous !
Again... thats why so many in Jail... and thats why hes hiding everything, because he has nothing to hide... what was that meeting about? Russian Adoptions you say? jfc get a clue already dude
btw, there is nothing to 'dig' for.... he obstructed justice. more than once. before your very own eyes.... guess you are one of those folks he was talking about that would support him even when he shoots someone.
