U.S. Vice President Kamala Harris confirmed early Wednesday that she is "proud" of her candidacy on President Joe Biden's ticket for the position of "Vice President," amid ongoing discussions about the health of the Democratic president following his disastrous performance in the debate against Republican rival Donald Trump last week. Commenting on the calls for Biden (81 years old) to withdraw from the presidential race and for Harris (59 years old) to replace him, the Vice President told CBS News, "I am proud of my candidacy for Vice President Biden," emphasizing that "Joe Biden is our candidate. We defeated Trump once and we will defeat him again." Prominent figures in the Democratic camp have started to publicly question Biden's health after his poor performance against Trump in the debate that took place on Thursday evening.
