CNN analyst David Gergen warned House Speaker Nancy Pelosi that she’s holding a “double-edged sword” by withholding the House-passed articles of impeachment from the Senate.

Joining Sunday night’s CNN Newsroom, Gergen — who was an adviser to former Presidents Richard Nixon, Gerald Ford, Ronald Reagan, and Bill Clinton — was asked to respond to Vice President Mike Pence’s chief of staff Marc Short’s assessment that Pelosi “will yield” eventually and send the articles to the upper chamber.
