Former U.S. President Donald Trump mocked President Joe Biden after the latter referred to his Vice President Kamala Harris as "Trump." In a post on Truth Social, Trump ridiculed Biden's slip, writing: "Twisted Joe started his press conference by saying: 'I would not have chosen Vice President Trump to be Vice President if I didn't believe she was qualified to be President.'" Trump added, "Great job, Joe!" Following Biden's gaffes during the press conference, Democratic sources told CBS News that dozens of Democratic lawmakers are expected to release statements within the next 48 hours calling for President Joe Biden to withdraw from the presidential race.
