Ex-senator says Democrat likely to risk revealing classified impeachment document from Pence aide

A former lawmaker expects one of the Senate Democrats to speak out about a classified letter from an aide to Vice President Mike Pence that has become part of the impeachment fight.

Claire McCaskill, who was a Democratic senator from Missouri from 2007 to 2019, told an MSNBC panel that her former colleagues are frustrated by the concealment of the document, which was admitted as impeachment evidence on Wednesday. McCaskill said their frustration could lead to a “risky” disclosure because they believe it was improperly classified.
