WASHINGTON — A former police officer charged with obstruction for telling a Jan. 6 rioter to remove a Facebook post about being in the U.S. Capitol testified Monday that he was "embarrassed" about having spoken to the man, who he claims duped him about his level of involvement in the attack.Michael Riley, who sent messages to Jan. 6 rioter Jacob Hiles shortly after the insurrection, when he was a U.S. Capitol Police officer, told jurors Monday that he believed Hiles when Hiles posted that he was forced into the Capitol by the pro-Trump mob.After another member of the Chesapeake fishing community tagged Riley in Hiles' Facebook post about entering the Capitol, Riley sent a private message telling Hiles to take down the part of his post in which he admitted going into the building.“I never intended for any of this to happen.”He later deleted his Facebook messages with Hiles because he was extremely upset, he testified, insisting he wasn't trying to obstruct any investigation.McNamara asked."
