Susan Hennessey and Benjamin Wittes do a quick summing up:

The first big takeaway from Monday morning’s flurry of charging and plea documents with respect to Paul Manafort Jr., Richard Gates III and George Papadopoulos is this: The president of the United States had as his campaign chairman a man who had allegedly served for years as an unregistered foreign agent for a puppet government of Vladimir Putin, a man who was allegedly laundering remarkable sums of money even while running the now-president’s campaign, a man who allegedly lied about all of this to the FBI and the Justice Department.

The second big takeaway is even starker: A member of President Trump’s campaign team admits that he was working with people he knew to be tied to the Russian government to “arrange a meeting between the Campaign and the Russian government officials” and to obtain “dirt” on Hillary Clinton in the form of thousands of hacked emails—and that he lied about these activities to the FBI. He briefed President Trump on at least some of them.

…

President Trump, in short, had on his campaign at least one person, and allegedly two people, who actively worked with adversarial foreign governments in a fashion they sought to criminally conceal from investigators. One of them ran the campaign. The other, meanwhile, was interfacing with people he “understood to have substantial connections to Russian government officials” and with a person introduced to him as “a relative of Russian President Vladimir Putin with connections to senior Russian government officials.” All of this while President Trump was assuring the American people that he and his campaign had “nothing to do with Russia.”

It looks bad, doesn’t it. Shady.

Mueller’s opening bid is a remarkable show of strength. He has a cooperating witness from inside the campaign’s interactions with the Russians. And he is alleging not mere technical infractions of law but astonishing criminality on the part of Trump’s campaign manager, a man who also attended the Trump Tower meeting.

Any hope the White House may have had that the Mueller investigation might be fading away vanished Monday morning. Things are only going to get worse from here.

Which could mean that larger things will eventually get better.
