Can he really blocks McGahn from testifying?

Who has already testified to Mueller. What he's doing is obstruction, again. So is ordering anyone not to cooperate.

no EP exist

We shall see if this is true.

Barring a rather bizarre Supreme Court decision.

However, if mcgahn chooses to defy congress, I think Donnie can pardon him from any criminal contempt charge.

Congress may have to dust off their inherent contempt powers if they want to actuallyy scare Trumpists with the prospect of incarceration.

Not a historian, but I don't think we've ever had such a situation when the president does what he damn pleases and his party and many others cheer him.

It really all goes back to the turtle refusing to even consider the nomination of Garland.

it's not just donald fraud and his gang. it's also mcturtle and enough republican control to prevent congress from effectively fighting back (the house now can investigate, but still can't pass laws). it's also the judiciary, which is more and more biased to the insane right wing. not just the supreme court but the entire judiciary.

then he's gutting the bureaucracy, preventing our institutions from tracking and delivering the truth about many, many things, never mind enforcing anything, which he's put a near stop to, except maybe to go after political enemies.

it's the non-stop assault on the truth from donald fraud, his supporters, his enablers, and the media. foxnews is obviously solidly in the "lie for the right-wing" camp, but the rest of the media either gives the lies more airtime or at a bare minimum lets the right-wing lies set the agenda even if it tries to refute the lies.

then there's electoral malfeasance on top of everything.

everything's corrupt, and it's all in the right-wing's favor.

It used to be limiting government but it is "government" that gave corporations all the tax freebies. It is the government that spends millions (trillions?) on the military, Perhaps still "pork" for things that the military does not need, did not ask. And, oh, this is rich: it used to be the government fighting "commies" and now Russia which is still our enemy.

has no jurisdiction. They can't do anything. It's literally in the Constitution.

he can delay it for 2 or 3 years.

Once waived, executive privilege cannot be asserted. Not that it can’t be held up in court for ages...

hopefully the judge will force Trump to pay legal fees for House attorneys and McGahn's attorneys.

1) McGahn already testified to Mueller, so that precludes any claims of privilege
2) Trump was attacking McGahn and House Dems on Twitter today, so any claims of privilege are lost here as well because that would not allow McGahn a chance to defend himself.
