Former Massachusetts Air National Guardsman Jack Teixeira says he's deeply sorry for all of the harm he's caused.  That's what the 22-year-old Dighton native told the judge at his sentencing hearing Tuesday where he was sentenced to 15 years in prison for leaking classified docs online. 

He shared intel about Russia's war with Ukraine and North Korea's nuclear ambitions on Discord and even acknowledged in messages on the platform that he could face criminal charges if he was caught.
