Former special counsel Robert Mueller will sit Wednesday for hours of testimony on Capitol Hill and it won’t change a single thing.

The conclusion of his two-year long investigation will still be that there was no proof of a conspiracy between Russians and President Trump’s 2016 campaign. Mueller will still abstain from determining whether Trump obstructed justice, though his boss, William Barr, has already made that call for him. And Democrats, regardless of what is said, will still push for impeachment, despite failing to point to any particular act that would justify it.

This is where we have been for the past four months, ever since Barr released the bottom line conclusions of Mueller’s exhaustive, 400-page report in March.

After that, Barr made almost all of the report public. Nothing changed.

After that, Mueller gave his first on-camera public statement on his investigation. Nothing changed.

Congressional Democrats this week have been saying that they hope Mueller can help bring his report “to life.” That’s because it’s dead. How many times can you resurrect a corpse?

Mueller has already stated that he won’t offer any information that goes beyond the contents of the report, which is kind of like Webster declaring that he won’t talk about any words that aren’t in the dictionary.

The Mueller report tediously documents every single episode related to Russia and Trump’s frustration with the invasive probe of his campaign and personal life. The report even goes so far as to remind Congress that regardless of what’s in it, they have the power to impeach a president at any time and for any reason at all.

Smart Democrats, of course, know that impeachment would blow up in their faces when they’re once again unable to find the Russia collusion ghost, so they’re hoping against hope that Mueller might give them some kind of wink or nod on the obstruction question. They’re looking for him to save them from themselves.

It’s not going to happen and we know that because he would have done it by now.

Dragging him to sit in front of Congress won’t change a thing.
