PHILADELPHIA (AP) — A glass ceiling is shattering at the Democratic National Convention as Hillary Clinton ascends to the presidential nomination with today's roll call of the states, making her the first woman to lead a major party into a White House race.

But as history is being made, hostility is being heard, too. Rhetorically, at least, die-hard Bernie Sanders' supporters also are breaking some glass, loudly protesting his treatment by the party and still cold to Clinton even as Sanders appeals for Democrats to unify and defeat Republican Donald Trump, whom he calls "a bully and a demagogue."

What was expected to be a tightly orchestrated convention instead showed its rough edges in the early going, starting with chants of "Bernie" during the opening invocation and boos at numerous mentions of Clinton's name.

First lady Michelle Obama gave a heartfelt endorsement of the candidate who engaged her husband in a fierce struggle for the nomination in 2008.

Liberal favorite Elizabeth Warren, senator from Massachusetts, and Sanders himself also gave the party something to cheer about Monday night.
