Welcome to The Beat. I'm Ari Melba reporting live from Washington today, where we have a special show for you tonight on this first day of Steve Bannon's criminal trial.

We're seeing these first sketches of the twice-indicted Trump aide in court with clues about the process as he faces up to two years in prison.

Former prosecutor John Flannery joins me here in Washington in person

tonight, and we'll hear directly from a top economic figure in the Biden White House, Brian Dease.

Plus, Pulitzer Prize winning columnist Gene Robinson and author David Corn, both here on set

with me right now. So we would argue that it is a big show or as good as any show

we can bring you. And we begin right now with the news about a new witness going to face this

House January 6 probe tomorrow. As a Trump White House aide who went so rogue, he was punished

for sneaking coup plotters into the White House. He worked for Peter Navarro, the now indicted aide, who pushed to overthrow the election.

And if you watch the beat, you may recall a little bit about Mr. Navarro's aid, Garrett Ziegler,

because we've reported on his role before.

We even asked Mr. Navarro about it.

Ziegler is the one who snuck in the people that had that Trump lawyer, Pat Cipollone, so mystified.

Ziegler is the one who lost his guest privileges over it.

And Ziegler is the one who had his own boss disowning his actions because even Navarro wanted no part of that military voting machine plot.

The first thing I did, I walked in, I looked at them and I said, who were you?

I waved in General Flynn and Sidney Powell on the 18th, on the Friday night of the 18th.

I didn't understand how they had gotten in.

For which Mark Meadows' office revoked my guest privileges.

I could no longer get people into the complex after that.

Was it wrong for your aid to facilitate that meeting?

I had no comment on that.
