A U.S. Capitol Police officer has been indicted on obstruction of justice charges after prosecutors say he helped to hide evidence of a rioter's involvement in the Jan. 6 riot.
The officer, Michael A. Riley, is accused of tipping off someone who participated in the riot by telling them to remove posts from Facebook that had showed the person inside the Capitol during the Jan. 6 attack, according to court documents.
He is due to appear in federal court in Washington later Friday.
Riley, who responded to a report of a pipe bomb on Jan. 6 and has been a Capitol Police officer for about 25 years, had sent the person a message telling them that he was an officer with the police force who “agrees with your political stance,” an indictment against him says.
The indictment spells out how Riley sent dozens of messages to the unidentified person, encouraging them to remove incriminating photos and videos and telling them how the FBI was investigating to identify rioters.
It wasn't clear if he had an attorney who could comment on the charges against him. A call to the U.S. Capitol Police wasn't immediately returned.
In a statement, Capitol Police Union chair Gus Papathanasiou said "we need to wait until all of the facts of the case are known and this officer has been given the opportunity to defend himself. All I ask is that everyone respect the process and let it proceed before rendering a judgment on this officer."
In the days after the attack, scores of rioters flaunted their participation in social media posts that bragged about their ability to get inside the Capitol. But then many started realizing it could be used as evidence and began deleting it.
An Associated Press review of court records has found that at least 49 defendants are accused of trying to erase incriminating photos, videos and texts from phones or social media accounts documenting their conduct as the mob stormed Congress and briefly interrupted the certification of Democrat Joe Biden’s election victory.
Experts say the efforts to scrub the social media accounts reveal a desperate willingness to manipulate evidence once these people realized they were in hot water. They say it can serve as powerful proof of people’s consciousness of guilt and can make it harder to negotiate plea deals and seek leniency at sentencing.
But making digital content vanish isn’t as easy as deleting content from phones, removing social media posts or shutting down accounts. Investigators have been able to retrieve the digital content by requesting it from social media companies, even after accounts are shut down. Posts made on Facebook, Instagram and other social media platforms are recoverable for a certain period of time, and authorities routinely ask those companies to preserve the records until they get court orders to view the posts.
