Rep. Michele Bachmann (R-Minn.) delivered a blistering critique of Hillary Rodham Clinton on Friday, insisting in a speech that the former secretary of state is not qualified to lead the nation's armed forces as president.

Clinton is "not commander in chief material," said Bachmann. She then ripped the Democrat for the "utter, abject failure" in Benghazi and said she "fails to inspire confidence in practically anything she touches."

Bachmann made her remarks before an audience of religious conservatives at the Faith and Freedom Coalition's "Road to Majority" conference in Washington. The 2012 presidential candidate announced last year that she is stepping down at the end of her current term. She made the announcement in the face of campaign finance investigations.

Bachmann quipped that Clinton has "made so many unforced errors" during her book tour during the past couple of weeks "that Barack Obama actually considered making her his new vice president," a dig at the gaffes of Vice President Biden.
