U.S. Capitol

The 46th president called for unity at a time America is facing huge challenges.

This comes amid ongoing threats to state Capitols across the country.

Charges say he shared photos on social media of him inside the Capitol on Jan. 6 and commented on a post saying he's wanted by the FBI.

"Those who made threats of violence at the rally in St. Paul should be investigated and held accountable," the letter states.
