Former President Barack Obama, on the third and penultimate night of the Democratic National Convention, delivered a speech skewering the job Donald Trump has done as president ― and lauding his “brother” Joe Biden for his character and political experience.

Trump has “shown no interest in putting in the work, no interest in finding common ground, no interest in using the awesome power of his office to help anyone but himself and his friends, no interest in treating the presidency as anything but one more reality show that he can use to get the attention he craves,” Obama said Wednesday night from Philadelphia.

Obama has, over the past four years, largely refrained from criticizing his successor, but he minced no words in his lambaste of the president during his DNC address.

“Donald Trump hasn’t grown into the job because he can’t,” the former president said. “And the consequences of that failure are severe: 170,000 Americans dead, millions of jobs gone, our worst impulses unleashed, our proud reputation around the world badly diminished, and our democratic institutions threatened like never before.”
