Donald Trump just spent 2 years waiting for a report on whether or not he received dirt from a foreign government to help his 2016 election. So his personal attorney announces he is going to talk with a foreign government on getting dirt to hurt a political rival.
I don't know how many tripwires this crosses. If Joe Biden's son was involved in something nefarious in the Ukraine, the United States Justice Department should investigate. Even Bill Barr couldn't sign off on this one. So the President was sending his personal attorney as his agent to pretty please ask the Ukrainians for dirt on Biden.
Rudy said that this would be "Very very helpful" to his client. If the Ukrainians do provide Rudy with negative information on Biden that is disseminated in hopes of helping Trump, this is a direct violation of the emoluments clause, because Rudy is requesting something that he already as defined being of value from a foreign government. It's nice when Rudy makes the case against his own client.
Eventually someone with the last functioning brain cell pulled the plug on the trip. This was Giuliani's brilliant defense on Fox News:
I’m not going to go because I think I’m walking into a group of people that are enemies of the president... I think this was a set-up."
So the trip that Giuliani set up was cancelled, because Giuliani said it was a setup. Notice it's not because it was a horrible idea, but a 'setup'. It's pretty clear that whatever modicum of control John Kelley had with Trump has flown out the window under Mick Mulvaney, and the approval process for craziness is getting less and less filtered.
The Last Days of Trump's Bunker could be very ugly.
