 Live from NPR News in Washington, I'm Korva Coleman. President Biden held an anticipated solo press conference last night. He doubled down on his decision to remain in the presidential race, despite calls from some members of his own party to drop out. They've cited his age and ability to lead the country for a second term. Prior to the press conference, Biden met NATO leaders, but at one point he misspoke. He referred to Ukrainian President Volodymyr Zelensky as President Putin of Russia. Biden then corrected himself.
