The U.S. Attorney's office announced an update on charges related to the U.S. Capitol insurrection soon.

As I cover that, my colleague @ColinKalmbacher will live-tweet the Aaron Mostofsky hearing.

The briefing is about to begin.

FBI Washington Field office's Steven M. D'Antuono is up first.

"We have opened 160 case files, and that is just the tip of the iceberg."

D'Antuono:

We have received more than 100K pieces of digital media.

He solicits more at 1-800-CALL-FBI

D'Antuono:

He credits pre-siege intelligence to the arrest of Proud Boy leader Enrique Tarrio before Jan. 6 lawandcrime.com/civil-rights/h…

D'Antuono defends the FBI's response before the siege, describing the challenge of distinguishing extremists' bravado from true threats.

Acting USA Sherwin is up:

He says he anticipates hundreds of cases.

The numbers will "geometrically increase."

Sherwin:

USAO charged 70 cases.

They have opened +170.

Sherwin describes the spectrum of potential charges, citing trespass, assault on local officers, federal officers, theft of potential national defense info, and felony murder as possible ones.

Sherwin:

"This is just the beginning."

Now after those charges are filed, then we have the ability to indict these individuals on more significant charges.

Sherwin:

"I just want to clarify that the initial charges we're filing, some of these misdemeanors, are only the beginning. They are not the end."

Sherwin:

The FBI, working with U.S. Attorney's office, are looking at cases that potentially include sedition and conspiracy cases.

Sherwin:

"We've also focused on an emphasis on" law enforcement.

"I think there are a lot of misconceptions about what happened in the Capitol," describing open-handed "combat" by rioters against law enforcement and the media.

Asked whether authorities are looking into the possibility that suspects were trying to take Congress members hostage, D'Antuono says they are looking into all possibilities.
