The former First Lady was chatting during a commercial break with Chris Matthews during an MSNBC town hall when a hot microphone picked up their conversation.
From the Washington Post:
The subject quickly turned to Christie, and Clinton wondered: "Why did he support him?"Of course it never occurred to Clinton that Christie might see Trump as the candidate best suited to clean up Barack Obama's mess.
Matthews explained that Christie and others who support Trump "want a future" politically.
"Did he have a debt?" Clinton mused.
