A contentious scene unraveled here Tuesday morning at a meeting of Texas delegates after one criticized Hillary Clinton, the presumptive Democratic presidential nominee and a favorite of Lone Star State Democrats.

For Michelle Obama, this election is about the kids. On the opening night of the Democratic National Convention, the first lady wove her vision for the next generation with her hope for the next president.

"This election, and every election, is about who will have the power to shape our children for the next four or eight years of their lives," she said, adding that Hillary Clinton is the only candidate "who I trust with that responsibility."

Democrats' attempts to put on a unified front on the first day of their convention in Philadelphia got off to a disastrous start Monday morning.

Primary runner-up Bernie Sanders was loudly booed when he spoke to his supporters after telling them they needed to vote for Hillary Clinton and her running mate Tim Kaine.

Update: Mayor Lee Leffingwell announced today that the city won't pursue hosting the 2016 Democratic National Convention.

Despite noting that “recent past conventions have injected $150 to $200 million into the [host] cities economies,” Leffingwell cited two hurdles to an Austin convention: facilities and transportation.

Leffingwell told reporters the DNC has very specific operational requests; foremost among that is a facility big enough for convention attendees.
