Kamala Harris made history on Wednesday when she accepted the Democratic nomination for vice president, while joining Barack Obama and Hillary Clinton to condemn President Donald Trump’s profound “failure” as a leader. Harris, the first black woman on a major party’s White House ticket, accused Trump of turning “our tragedies into political weapons.” And she urged Americans to vote for Joe Biden, “a president who will bring all of us together.” Shortly before Harris spoke, America’s first black president, Barack Obama, delivered his own condemnation of Trump — and appeal for Biden’s election. Obama said that on handing over the White House to Trump in 2017, he thought the Republican “might show some interest in taking the job seriously; that he might come to feel the weight of the office and discover some reverence for the democracy that had been placed in his care. But he never did,” Obama said.
