President Joe Biden appeared to be at odds with his top scientist in the pandemic fight, Dr. Anthony Fauci, about whether former president Donald Trump should urge his supporters to get vaccinated, given a poll that shows they are the Americans most likely not to get the shots.

"Should President Trump help promote the vaccine amongst skeptics, sir? Especially those Republicans who say that they’re not willing ... ," a reporter at the White House asked Biden at the end of an event Monday.

"I'm hearing a lot of reports from serious reporters like you saying that. I discussed it with my team, and they say the thing that has more impact than anything Trump would say to the MAGA folks, is what the local doctors, what the local preachers, what the local people in the community say," he responded. "So, I urge all local [doctors] and ministers and priests to talk about why it's important to get that vaccine, and even after that, until everyone is, in fact, vaccinated to wear this mask."
