jack teixeira is a 21—year—old us airman from massachusetts and he's currently facing 15 years in jail. he's been charged with leaking classified documents that he's alleged to have posted on the online chat forum discord earlier this year. the documents revealed us assessments of the war in ukraine as well as sensitive secrets about american allies. when the fbi finally arrested teixeira on the 13th of april, the new york times and other journalists had already identified him as a suspect. how they did it is a fascinating story in itself. and two of them are here now. one of them, haley willis, works in the visualjournalism team at the new york times. haley, welcome. now, you were outside his home as the fbi turned up. talk us through what happened. yes, that's right. thank you for having me, katie. so we identified jack teixeira through some digital sleuthing, which we'll talk about in a bit more, on wednesday night, very late wednesday night.
