VIDEO: Hillary Clinton sees 'biggest crack' in glass ceiling

PHILADELPHIA -- Hillary Clinton tells Democrats they've "just put the biggest crack in that glass ceiling" by nominating her for president.

Clinton was speaking to the Democratic convention by satellite video, and offering this message to any little girls who might have stayed up to see the historic moment Tuesday night: "I may become the first woman president, but one of you is next."

Earlier in the evening, Clinton became the first woman in the U.S. to be nominated for president by a major political party.
