Vice President Kamala Harris wished her husband, second gentleman Doug Emhoff a happy anniversary on Thursday ahead of her acceptance speech at the DNC. The couple are celebrating their 10th wedding anniversary.

"To the best partner I could ask for: Happy anniversary, Dougie," Harris posted on social media, with a picture of the two visiting campaign headquarters in Wilmington the day after she announced her candidacy.

Earlier Thursday, Emhoff did the same, posting a slideshow of photos of himself and Harris.

"Ten years of marriage, forever to go," Emhoff wrote. "Happy anniversary, @WRQ11HGNB. I love you."

Angie Gialloreto, 95, has attended every Democratic National Convention since 1976, when Jimmy Carter was on the ticket.

Since the 99-year-old former president could not attend this year’s DNC due to his health issues, Gialloreto is the oldest delegate to travel to Chicago, where she will watch Harris accept her party’s nomination.

The Pennsylvania native told ABC News the possibility that Harris could become the first woman to serve as president was a long time coming because women "have taken a back seat many years and now we’ll have a leader."

When asked how she would celebrate if Harris ends up victorious during the November general election against Donald Trump, Gialloreto said she will focus on "getting ready for the next election of local candidates."

The morning after accepting his party's nomination for vice president, Walz gathered in Chicago with former staff, family, friends and former students -- including some of the football players who appeared on-stage Wednesday night at the United Center.

ABC News spotted Walz at a Chicago hotel on Thursday morning.

During that meeting, he mingled with several of his former Mankato West High School students over an informal breakfast, according to a source familiar with Walz's movements. Some of those who met with Walz at the hotel were observed by ABC News donning "Harris-Walz Alumni" T-shirts.

Earlier in the day, Walz posted a video on X showing him hug and greet the students backstage at the convention.

Former campaign managers and senior staffers who worked Harris through the years shed light on how she prepares for big speeches.

They said she’s a trial lawyer at her core, and so preparation was key as well as being ready for audience reactions.

In crafting a speech, she would start with themes, outline and then focus in on what she wanted to say well in advance. She would be intimately involved in every speech, making edits and collaborating with those around her.

They said like most people she gets nervous, but would relax, review the remarks, save her voice, conserve energy and rest up.
