A Bexar County jail guard is under investigation for being present at Wednesday's riot at the U.S. Capitol building. Lieutenant Roxanne Mathai of San Antonio posted pictures of herself on social media, which were forwarded to her boss, Sheriff Javier Salazar. The sheriff says the screen shots have been sent to the FBI to see if there could be administrative or criminal charges. Salazar says there was an order for the crowd in D.C. to disperse, and if Mathai stayed, that could result in her arrest.
