“When President Harris and I took a virtual tour of a vaccination center in Arizona,” Biden said, pausing briefly after referring to Harris as the President, perhaps realizing he made a mistake.

In December, while the election was still being contested by President Donald Trump, Biden previously referred to Harris as “President-elect Harris.” This was described as simply his “latest gaffe” by the international media.
As National File reported, “On February 2, ‘Vice President Kamala Harris spoke with Canadian Prime Minister Justin Trudeau on Monday, marking her first call to a foreign leader since entering the White House.’” Also in February, “Harris spoke with extensively with President Macron” and “‘and expressed her commitment to strengthening bilateral ties between the United States and France and to revitalizing the transatlantic alliance.’”
Biden also holds a unique, seemingly sparse schedule compared to other U.S. Presidents. He starts working at 8 a.m., and retires to his quarters no later than 7 p.m.
Biden also appears to have had many senior moments since taking office. Immediately after taking the White House in January, he signed a jaw dropping number of executive orders. When one was displayed on his desk, he said, “I don’t know what I’m signing,” then proceeded to sign it anyway.
Also in January, Biden was caught on a hot mic saying “Salute the Marines” as he walked past two Marines. Many believe he was instructed to salute by an earpiece, and instead said it aloud.
