Continuity mistake: Towards the beginning of the film, Mike is in a diner with a woman. A group of people walk up and they have a conversation. Mike sets down his white cup on the table. This cup continually vanishes and reappears throughout the scene. (00:12:05)
Continuity mistake: The wound on Mike's left forehead changes position between getting it from his fall from the roof to the end of the film.
Continuity mistake: When the Speaker is asking if anyone has contact with anyone in the white house (besides Banning) his hands are crossed left over right then right over left depending on the shot. (00:47:05)

Continuity mistake: When the secretary of state is punched to the floor before giving up her Cerberus code, she falls and lands a good distance from 2 blood pools on the floor. When the camera changes to a close up, she is right over said pools of blood. (01:10:50)
Answer: Forbes slipped up by mentioning the head bad guy's name. And, as good an agent as Forbes was, it is highly doubtful, not to mention suspicious, that he'd still be roaming around by himself this long after the fall of the White House. Plus Mike ain't stupid and most likely smelled a rat. And he was correct. Forbes was dirty.
