A UPS employee in New Jersey is facing federal charges after an anonymous tip and multiple coworkers notified the FBI that he allegedly participated in the siege on the U.S. Capitol on Jan. 6.

Donald Smith is charged with knowingly entering or remaining in a restricted building or grounds without lawful authority, disorderly and disruptive conduct in a restricted building or grounds, violent entry and disorderly conduct on Capitol grounds, and parading, demonstrating or picketing in a Capitol building, according to U.S. Department of Justice documents.

More than a dozen New Jerseyans have been charged in connection with their alleged involvement at the Capitol.

The FBI said that on or about Jan. 9, it received an anonymous tip claiming that Smith had stormed the Capitol, had "videos on his phone and was bragging about it at work." Subsequently, a person who identified themselves as Smith's coworker told the agency, "He says he was in [House Speaker] Nancy Pelosi's office and that it was the best day of his life. I do not condone these actions and would like to report him."

At least three other people came forward identifying Smith as a UPS employee, specifically referencing a gray scarf he regularly wore to work and was allegedly seen wearing on surveillance.

So far the FBI has only able to interview two of the four non-anonymous witnesses.

Cell phone data showed Smith traveling from Lindenwold to Washington D.C. on the morning of the 6th, and returning to Lindenwold that night, according to the FBI.
