Moderator Kristen Welker pressed Trump on his comments earlier this week attacking Dr Anthony Fauci as a disaster and other health experts as idiots.

Trump downplayed his differences with Fauci before criticising him for reversing his guidance on using masks.

Trump added, I think hes a Democrat, but thats okay.

Two fact-checks: Fauci changed his advice on face masks because additional evidence revealed they could help limit the spread of coronavirus from those who are asymptomatic or have not yet developed symptoms.

And Fauci is not a Democrat. The highly respected infectious disease expert is not registered with either party, according to his voter registration.
