If he's really "looking forward to it", he's a fool IMO. There's no upside for him talking to the FBI/special counsel.
Part of it is political/public positioning. Another part is just how much info does Trump have on Mueler/clinton lawyers in this probe. Seems the worm is turning..FBI.....
Seems Herr Mueller is "The Insurance". Not to get rid of Trump, but to insure he does not prosecute them.....Mexican Standoff so's to speak.
I think a lot is determined by whether the real "deep state". Lower level , non-political FBI-ABC government employees wish to rid themselves of the stench of obama-Clinton corruption.
I know one thing... would love to play a night of poker with Trump.
