Take him to court! The Dems refused to do so. So much for your feckless leadership!
They already took Don McGahn to court, and won at every level.
Does the name fast and the furious and executive privilege ring a bell? If so do you recall who used it and whom it was given to?
Yes. Obama ASSERTED the Privlege thru Eric Holder in the Congressional inquisition, when asked specific question involved with executive privilege.
That is how executive privilege is LEGALLY done.
Trump did no such thing.
He ordered all white house staff and administration, not to show up in Congress and not to turn anything at all over to Congress.
Which is illegal, obstruction of Congress....
Congress represents "we the people", and Trump simply SPAT in our faces.
