Ex-Trump officials face Congress over security breaches, including a military plan leak to a journalist.

Top intelligence officials from the Trump administration will testify before Congress this week, addressing national security threats and a recent scandal involving the leak of sensitive military plans through a group chat. The leak occurred when The Atlantic's editor, Jeffrey Goldberg, was inadvertently included in a chat discussing plans to attack Houthi targets in Yemen. Lawmakers from both parties are set to question the officials about the incident and broader security measures, while also reviewing the annual threat assessment, which highlights concerns like Chinese espionage, ransomware attacks, and terrorism.
