Federal authorities have arrested a Donald Trump supporter caught on video bragging about macing police at the Capitol on Jan. 6.

Samuel Lazar, who was arrested in Pennsylvania on Monday, spent the months after the Capitol attack attending political events in support of the former president and his political allies. The case against him was unsealed on Tuesday.

Lazar faces felony charges, including assaulting, resisting or impeding certain officers as well as obstruction of law enforcement during civil disorder. He also faces a charge of knowingly entering and remaining on restricted grounds.

Lazar has been featured in at least half a dozen photos with Doug Mastriano, a Pennsylvania state senator who helped spread Trumps lies about a stolen election and even chartered buses to Washington, D.C., on Jan. 6 using campaign cash. Mastriano and Lazar were pictured together on numerous occasions before the Capitol attack and were most recently photographed posing together at an event for Trump lawyer Rudy Giuliani in May (at that time, Lazars photograph was featured on the FBI s website).
