Trump suggests he might fire Fauci

On election night in 2000, voters were told the crucial state of Florida had gone to one candidate. Then, they were told it actually went to another. Then again, they were told it was in fact too close to call.

Today, amid unprecedented concerns about reporting the election results in a timely manner, broadcast news networks are bracing for an extended period of uncertainty and trying to set expectations accordingly -- both for audiences and within their own offices.

"We have to get election night right," James Goldston, president of ABC News, said in an interview with ABC's daily podcast "Start Here." "On the flip side of that, I think what the audience has to expect on that night... I would use two words: uncertainty and patience."

Biden will make several stops in Philadelphia on Sunday ahead of Election Day, as Democrats try to juice turnout in a city where they need to perform well to offset the expected strong showings from Republican in rural parts of the state. 

Hillary Clinton won 82.3% of the vote in Philadelphia in 2016 with 584,025 - 4,781 fewer votes than President Barack Obama received in 2012, and 10,192 fewer than he received in 2008. 

Given that President Trump won Pennsylvania by roughly 44,000 votes four years ago, Democrats know it's important to get as many people to vote in Philadelphia as possible.

Trump spoke to a packed crowd of supporters in Washington, Michigan, declaring he was going to win the state and periodically complaining about the frigid temperature at this first of five rallies on Sunday.

At one point he compared himself to Luciano Pavarotti, who he called "the greatest of all divas," who would leave appearances if he didn't feel up to singing. Trump ultimately said that while he feels like Pavarotti, but that he didn't consider himself a diva, which is why he stuck around to finish his remarks in the cold.

He also said that if he didn't win the state four years ago, he wouldn't have been in Michigan on Sunday.

"I love the people of Michigan. We won. We won. It's worth it. It's worth it. It's worth it. It's worth it," he said. "We won last time, right? It's worth it. If we didn't win last time, I probably wouldn't even be standing here. I'd get up here and say no thanks."

Biden is adding a stop in Ohio to his schedule Monday, making a visit to Cleveland to "discuss bringing Americans together to address the crises facing the country and winning the battle for the soul of the nation," according to the campaign. 

This is in addition to Biden's previously advised "barnstorm" across Pennsylvania, with Biden, Harris and their spouses -- all fanning out across the state ahead of Election Day. 

This will be Biden's third visit to the Buckeye state since late August.
