In an elevator, the security guard blurted 'I love you' at Joe Biden. She endorsed him for President one viral video later.

She was last seen blurring "I love you" to Joe Biden as she led him to a New York Times editorial board meeting in an elevator last December, part of an interaction that went viral as the Biden campaign casted her adulation as a bigger deal than the endorsement of the news organization he lost.

Jacquelyn Brittany, a 31-year-old African American security guard, did something else for Biden on Tuesday night: she became the first person to put his name on presidential nomination. Her role was first revealed in The Washington Post.

For the Biden campaign, Jacquelyn epitomized the complexities of primaries: Biden's dreams, which others spurned, rested on Black women and working-class voters, who would ultimately revive his campaign.

She extolled Biden as "my friend" on Tuesday.

"I just take important people up my staircase," said Jacquelyn, who asked for her first and middle name, Brittany, to be identified by The Post. "I was able to tell you in the short time I spent with Joe Biden that he has always seen me."

"I knew he would take my story with him even as he went into his important meeting," she said.

She compared her impression of Biden with Trump, as some have on the first two nights of the convention.

"Joe Biden is more than just himself having space in his heart," she said.

Before her nomination remarks, Jacquelyn said in an interview with The Post that she had supported Biden since he was a running mate for Barack Obama. "I like Joe. I really liked him, "she told me.

She said she takes hope in his life story and the tragedy that he has endured — the loss of his first wife and daughter in a car crash in December 1972 and of his son in May 2015 due to brain cancer.

"He has been through so many things. Yet outwardly he does not reveal it. He could feel it inside —And I'm that kind of girl,' she said, adding that her outward cheer masks a tough life, including child-care stints.

Jacquelyn said she hadn't known she'd be recorded for the episode of Times' television series, The Weekly, which featured Biden's visit to the news organization. But in December she chatted with an aide before Biden arrived for his interview and revealed she was thrilled to be escorting him upstairs.

"He was really really, honestly good to people until he came in. We are not getting that from anyone, "said Jacquelyn.

Jacquelyn was quiet for much of the elevator ride-She's not talking to guests she's escorting unless they're talking to her first — but her mind has been racing. "I kept thinking to myself, this was a guy I wanted to lead the country," she said, adding that she felt it could only be her chance to speak to him.

The aide urged her, indicating that the former vice president should say something. Jacquelyn turned to look at Biden and he grinned at her, saying "Hello," she remembered.

"It's my moment," she recalled thinking.

"I love you," she explained to him. "I am. You 're like my favorite. "(She told The Post in that sentence that she regretted saying" like.)

Biden thanked her and asked if she had a smartphone, and the two posed with her phone for a selfie that he had taken. As Biden took the shot, she said, she realized suddenly that the exchange was caught on camera.

The Times endorsed two of Biden's primary foes — Sens. Elizabeth Warren (D-Mass.) and Amy Klobuchar (D-Minn.). Yet Biden jumped on his moment with Jacquelyn when asked about the snub: "I got something better. I got to meet Jacquelyn, "he told Iowa, in Waukee.

Jacquelyn said she's been bristling at the comments online saying she's just been star-struck by Biden right now.

She said she had escorted Oprah Winfrey into the building a week ago and had not made a big show of it.

He said she never escorted President Trump and did not.

"I keep thinking, 'If he comes, I'm going to take off the day'"

She joined Sen. Christopher A. Coons (D-Del.) and Rep. Lisa Blunt Rochester (D-Del.) in nominating Biden ahead of roll call voting on Tuesday night.

Jacquelyn has watched other Democratic conventions and she said it was "overwhelming" to nominate Biden.

"I never thought I 'd be capable of doing this," she said. "I never thought I should have been worthy enough to do this."
