Democrats kicked off their convention Monday with a who's who of guests who all touted Vice President Kamala Harris' run for the White House.

Several topics came up during the night including the future of reproductive rights and Project 2025.

Harris made a surprise appearance after several Democratic VIPS took the stage, including Rep. Alexandria Ocasio-Cortez.

The main stars of the night were some of the Democrats' longstanding figures including Secretary of State Hillary Clinton.

But the main spotlight came as President Joe Biden spoke to the cheering crowd, reflecting on his four years as president and his decision to "pass the torch" to Harris.

Goldwyn said the choice between Harris and Trump is between "two very different futures" for our middle class, reproductive rights, climate, security, schools and "the future of our very democracy."

He said Harris has a message for America.

"It is a message that's joyful, not mean-spirited, a message of public service, not self-service, a message of optimism and opportunity, not chaos and division. A message that has woken us up to who we are, to who we've always," he said.

NY Gov. Kathy Hochul slams Trump

New York Gov. Kathy Hochul made several jabs at former President Donald Trump during her speech at the convention.

Hochul cited Trump's history of stiffing workers, sexually harassing women and his recent conviction in a Manhattan court.

"Donald Trump was born a New Yorker, but ended up a fraud, a philanderer and a felon," she said.

"New Yorkers are sick of it. It's no wonder he had to flee to Mar-A-Lago. Sorry about that, Florida," Hochul added.

The governor touted Harris' work in bringing new jobs to New York state and stressed Americans must vote to protect the middle class and abortion rights.
