Vladimir Putin has freed a former U.S. Marine after more than four years in a Russian prison, U.S. officials told Reuters. Russian authorities accused Gilman of being drunk and kicking a police officer during his stay. Russian authorities later extended his sentence after accusing him of assaulting prison staff, allegations his advocates have denied. Advocates have accused Russian prison guards of torturing Gilman and injecting him with mind-altering drugs, which they say contributed to his hospitalization. Russian official Yuri Ushakov informed Trump aides last week that Putin had approved the move.
