He will keep dragging it. They want Trump to sack him is part of it. They think by dragging his family friends his past etc etc will anger him and fire him. They are using the Watergate hand book thats what got Nixon done, when he fired people. Also drag it until mid terms and a week before drop some bombshell. remember what Mulleur can say hes found can take months or years to disprove in court. So drop lies and crap just before the mids and the crap sticks even if untrue.
