A strange video of U.S. President Joe Biden has gone viral, showing him appearing "frozen" for moments, which will complicate efforts to prove he is capable of serving a new term if he wins in the upcoming November elections. The video was captured during a celebration held at the White House garden, where the 81-year-old president is seen frozen while dancing around him to the music of a performance. The footage shows Biden smiling, while Vice President Kamala Harris and members of George Floyd's family dance. The president remained still for approximately 20 seconds before George Floyd's brother put his arm around him, prompting Biden to smile and place his hand on his chin, but he stayed motionless. This video is not the only one raising concerns about the health of the man who serves as the Commander-in-Chief of the United States Armed Forces.
