President Joe Biden was decidedly not in the spirit of celebration at a White House ceremony for Juneteenth, the new federal holiday recognizing the end of slavery.

The aging president appeared frozen in place as dozens of Black partygoers, including Vice President Kamala Harris, danced and clapped to music in a clip first highlighted by the campaign account for former President Donald Trump. “Lights are on but no one's home,” his team wrote on X, according to Fox News.

The bizarre moment came during a performance by gospel singer Kirk Franklin and was broken only when Philonise Floyd, the brother of George Floyd, noticed Biden's vacant stare and put an arm around him. The president smiled as Floyd whispered something in his ear and bumped his fist.

Republicans were quick to jump on the meme-worthy moment.

“Why isn't Biden moving?” the Republican National Committee's rapid response account questioned on X.

“Lights are on but no one's home,” President Trump's campaign posted.

“Who said Biden's got no rhythm?” quipped Sen. Mike Lee, R-Utah.

The White House, which did not respond to a request for comment by the outlet, has been under siege since an article last week by the Wall Street Journal where dozens of Republican and Democrat officials confided they are genuinely worried about President Biden's advanced age. At 81, he is the oldest ever occupant of the White House and would end a second, four-year term at the geriatric age of 86. Allies say he is alert and ready for the responsibilities of the world's most demanding job, but a few only said so after receiving a demand from the White House that they change their comments in the story.

Other instances of Biden's senior moments have gripped the internet over the past year. He appeared lost and nearly fell down a small flight of stairs at the G7 Summit in Japan. He began a national address only to forget he was live on-air. The cascading series of events have even made their way to grade school-age children who dressed up as a confused President Biden for Halloween. President Trump has joked that Biden's staff is feeding him stimulant drugs to keep him mobile and requested both candidates take a drug test before the first debate.

When a top advisor to former President Barack Obama suggested he step down for the good of the country, Biden lashed out in private, calling the fellow Democrat a “prick.” Still, allies are not wrong to question whether the Democratic Party is making a grave error by running an incumbent who is not only the oldest but also the most unpopular at this point in his first term. Harris, who is even more unpopular, would likely face an internecine war among other high-profile Democrats if the party were to pivot and replace Biden ahead of the Democratic National Convention in August.
