Top officials in the Trump administration discussed a military operation in a group chat on a commercially available messaging platform with a random member of the media added to the chat without anyone bothering to look at who else was in the chat. Senator Mark Warner, top Democrat on the Senate Intelligence Committee, shares his reaction to the news with Rachel Maddow.

Donald Trump says the scandal over his top officials discussing secret military plans in an unsecured group chat is just a "glitch" in an otherwise perfect first two months in office. Rachel Maddow looks back to help Trump jog his memory and realize that "perfect" is probably not the best word for what has happened so far in Trump's second term.
