Twenty-one-year-old Hunter Robertson walked out of the U.S. District Courthouse in downtown D.C. on Wednesday after testifying in an attempt to take some of the heat off his father, Thomas Robertson. “I think he’s being treated unfairly by all the court systems and the country,” Robertson told WUSA9 in an exclusive interview. “I think he’s being treated unfairly by everybody.” The younger Robertson testified under oath that at least one of the guns investigators found in his dad’s home, an M4 rifle seen in court documents sitting on Thomas Robertson’s bandstand, belonged to him, not his father. Assistant U.S. Attorney Elizabeth Ann Aloi told U.S. District Judge Christopher Cooper the statement conflicted with what Robertson’s son told investigators at the scene of the search. “Absolutely not,” Robertson said. “And I’ve never met with her before and I’ve never spoken with any agents about that issue before. That’s not true.” » Subscribe to WUSA9: https://bit.ly/2lO8e2F FOLLOW US ON SOCIAL MEDIA – Twitter: https://twitter.com/wusa9 Facebook: https://www.facebook.com/wusa9 Instagram: https://www.instagram.com/wusa9 NEWS TIPS – Email: newstips@wusa9.com We're tracking all of the arrests, charges and investigations into the January 6 assault on the Capitol.
