Washington | Vice President Kamala Harris challenged former president Donald Trump on Sunday (Monday AEDT) for refusing to do what she has done recently: release a report on his health, sit for a 60 Minutes interview and commit to another presidential debate.

“It makes you wonder: why does his staff want him to hide away?” Ms Harris asked the crowd at a rally in a packed college basketball arena in Greenville, North Carolina. “One must question: are they afraid that people will see that he is too weak and unstable to lead America?”
