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.

First lady Jill Biden is expected to speak Monday night at the DNC and, according to a source familiar with her remarks, will focus on the president's strength and character, as well as make clear her support for Vice President Kamala Harris.

The first lady will call on Americans to come together "with faith in each other, hope for a brighter future, and love for our country," the source said.

She will be introduced by a video highlighting key moments from her time in this role, and the issues she has focused on in her public life, according to a source familiar. The video will include Vivian Wierwille from New Hampshire, who gave a memorable introduction of Dr. Biden in March 2021 at Christa McAuliffe Elementary School during the First Lady's tour to highlight safely reopening schools after the pandemic.

While these remarks may be her last big address in her role as first lady, her office says she plant to continue to focus on her work in the next six months.

"Over the next six months, the First Lady will continue to champion the causes that have defined her public life: supporting military families, advocating for increased educational opportunities, working to end cancer as we know it, and advancing women's health research," Elizabeth Alexander, the First lady's communications director said in a statement.

The source says that the first lady will "of course" be out on the trail for Harris this fall.
