Biden misspoke in a speech he gave on Thursday, according to Fox News.

“When President Harris and I took …” Biden said

“….a virtual tour of a vaccination site in Arizona not long ago, one of the nurses on that tour injecting people, giving vax each shot, was like administering a dose of hope.”

Biden announced that he and his administration will achieve its goal of 100 million vaccines administered in 100 days on Friday, on the 58th day of being in office.

65% of people aged 65 and older have received at least one dose of a Covid-19 vaccine.

Once Biden referred to VP Harris as “president-elect.”

“I took it to instill public confidence in the vaccine. President-elect Harris took hers today for the same reason,” Biden said.

Biden always seems tongue-tied.

Harris seemed to accidentally dub herself commander-in-chief.

“A Harris administration, together with Joe Biden as the president of the United States,” she said.

“The Biden-Harris administration will provide access to $100 billion in low-interest loans and investments from minority business owners,” she continued.

Biden called his opponent Sen. Corey Booker the president.

“The fact is that the bills that the president, excuse me, the future president, that the senator is talking about, are bills that were passed years ago and they were passed overwhelmingly.”

Booker quipped, “Well first of all, I’m grateful that he endorsed my presidency already.”
