The fifth Democratic presidential debate had an episode that awakened the laughter of those present and the audience. The unusual moment starred Joe Biden and Kamala Harris.

The former vice president said Wednesday that his 2020 candidacy is backed by the only black woman who was elected senator.

“I have more people supporting me in the black community … because they know me, they know who I am, three former chairs of the black caucus, the only African American woman that’d ever been elected to the United States Senate, a whole range of people,” Biden said, according to Fox News.

However, a few feet away, sharing the panel, was the current senator from California and also candidate Kamala Harris.

Harris, who is the daughter of immigrants from Jamaica and India, laughed because she obviously had not offered her support to Biden.

“I’m right here,” Harris said, raising her arms before laughing with the rest of the audience, The Hill said.

Biden’s presidential candidacy was endorsed by former Illinois Democrat Carol Moseley Braun, who was the first black woman to be elected a U.S. senator.

Harris became the second black woman elected to the Senate in 2016, a fact that Biden apparently overlooked Wednesday as he tried to promote his support among black voters.

Harris was quick to point out the oversight on Twitter.

“Proud to be the second black woman elected to the U.S. Senate. #DemDebate,” tweeted the Democratic senator and presidential candidate.
