President Joe Biden referred to his vice president as "President Harris" during a speech on Thursday.
"When President Harris and I took ..." said Biden before taking a short pause, "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."
In December, Biden mistakenly referred to Harris as "president-elect," while Harris has also accidentally dubbed herself commander-in-chief.
Biden made a similar slip during a Democratic debate in July 2019 while criticizing Sen. Corey Booker's (D-NJ) criminal justice plan.
"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," said Biden.
