One year ago, journalist Jose Antonio Vargas revealed to the world that he was an undocumented immigrant — building his entire career, which included time at The Washington Post and The Huffington Post, on a lie. Vargas looks back at the past year in an interview with BuzzFeed, where he considers the weirdness of becoming an activist, his friends lost (many in the news industry), and his friends gained (Mark Zuckerberg, Aaron Sorkin). Great piece.
