Meantime, President Trump had strong words on Twitter on Monday for Special Counsel Robert Mueller and the Russian Investigation.

“Disgraced and discredited Bob Mueller and his whole group of Angry Democrat Thugs spent over 30 hours with the White House Councel (sic), only with my approval, for purposes of transparency. Anybody needing that much time when they know there is no Russian Collusion is just someone… looking for trouble,” the president tweeted.
