I agree. The Democrats are betting heavily on retaking Congress and they want Mueller to find ANYTHING they can use in an attempt to impeach President Trump. If the Republicans in Congress don’t wise up quickly, the Democrats will be successful and will be “in power” from then on. Republicans will never regain Congress OR the White House. They will stack the Supreme Court to make sure that any legislature is passed by either voting or jurisdictional edict.
This looks a lot like the charges against Manafort, where Mueller is going way beyond his initial mandate and found some money moving around somewhere that could be construed as "laundering," for which a Federal prosecutor could indict just about anyone.
If the Dems want to go the impeachment route, they can use any excuse the want if they retake the House.
I'm almost inclined to say, "bring it on," because I'd like to see Maxine Water's head on a pole on the Mall along with the others.
