Think about Pelosi's statement that "It just isn't worth it" to impeach the President.

What purpose does the Mueller probe then serve? He cannot indict a sitting President. The only logical outcome from the Russia Investigation was to gather evidence of the "high crimes and misdemeanors" allegedly committed by POTUS to be the basis for an Impeachment by the House and removal by the Senate. Absent the political will to remove Trump, Mueller serves no point. We've just been dragged through this bullshit for 2+ years.

I wonder if Nancy is trying to get in front of these items:

1. Trump is coming back to Congress for more Wall funding and she doesn't want a shutdown.

1. AOC has effectively taken over the Democrat Party and Pelosi will not survive as Speaker once more socialists join the ranks in 2020.

So, regarding Muller, "What difference, at this point, does it make?"
