Michael Flynn exited a federal courtroom Tuesday without receiving a sentence, after a judge berated the former Trump national security advisor for being an unregistered foreign agent of Turkey. "Arguably, you sold your country out," the judge told Flynn, in addition to asking prosecutors why they didn't request any jail time for Flynn's behavior.

As Flynn left the courtroom, demonstrators shouted competing chants, with apparent Flynn supporters yelling USA, while counter-protestor yelled "Lock him up!" Flynn famously said "Lock her up!" about Hillary Clinton in a speech he delivered at the Republican National Convention.
