With three days until Election Day, and President Donald Trump and former Vice President Joe Biden racing toward Nov. 3, more than 91 million Americans have already cast their ballots -- an early voting record.
On Saturday, Biden's top surrogate, former President Barack Obama, is joining him for the first time on the trail with drive-in rallies in Flint and Detroit.
Trump has four rallies in Pennsylvania as both candidates plan to "barnstorm" the state they deem critical in the final days before the election with the contest overshadowed by coronavirus cases rising there and in nearly every battleground territory.
Vice President Mike Pence has a pair of rallies in North Carolina -- a state Trump won by four points in 2016. California Sen. Kamala Harris is campaigning in Florida as Democrats vie for the state's 29 electoral votes key to Trump's pathway to the White House.
Here is how the day is developing. All times Eastern.

Trump slams SCOTUS absentee ballot decision
At the second of his four Pennsylvania rallies on Saturday, President Donald Trump railed over a recent Supreme Court ruling allowing absentee ballots in the state to be counted after Election Day in Pennsylvania and North Carolina.
“I've had many disappointing opinions from the Supreme Court, I will tell you,” Trump said at the rally in Reading. "That was a terrible decision."
He also conflated the likely delay in election results due to the historic increase in mail-in ballots with voter fraud, of which there is very little evidence, and baselessly claimed votes counted after Election Day would be “when the cheating’s gonna take place."
"Do you know when the cheating’s gonna take place? From the third to whatever the date it is that they gave," he said, calling the deadline extension "disappointing."
"That was a very political decision, I have to say," he said.

Who Trump is courting in Pennsylvania on Saturday
President Trump's Pennsylvania rally blitz on Saturday is primarily taking him to GOP strongholds to excite supporters and activate Republicans who may not have voted four years ago -- a bid to supercharge Election Day turnout to offset any Democratic gains in the suburbs.
Stop 1: Bucks County
Bucks County is 25 miles north of Philadelphia and the fourth-most-populous county in the state. It's Trump's only stop on Saturday to an area that isn't reliably Republican. While it's gone blue in every presidential election since 2000, the margin has tightened in recent years. Hillary Clinton won Bucks County by fewer than 3,000 votes in 2016. Demographically, Bucks County is 88.1% white, with 40.5% of residents holding bachelor's degrees or higher, according to the 2019 census.
Stop 2: Berks County Trump stopped next in Reading, the seat of Berks County and the fifth-largest city in Pennsylvania. Berks County came close to flipping for former President Barack Obama in 2012, where he lost by under 2,000 votes. Trump closed that gap four years ago, seizing the lion's share of the vote by 18,000. Demographically, Berks County is a little more diverse than Bucks. The census estimates that as of 2019, 86.9% of Berks County residents identified as white and 22.5% identified as Latino -- compared to 5.7% in Bucks County. Only about 24.5% of Berks County residents hold degrees.
Stop 3: Butler County Trump will travel next to Butler County in western Pennsylvania, another Republican stronghold since 2000. He handily trounced Clinton here in 2016, receiving more than 61,000 votes compared to Clinton's 26,834. According to The Associated Press, more than 10,000 Republicans in the county did not vote in 2016. Butler County is overwhelmingly white, according to census estimates (95.8%), and only 35.4% of residents hold bachelor's degrees or higher.
Stop 4: Lycoming County The final stop will be Montoursville in Lycoming County -- yet another GOP area that has not been hotly contested to as far back as 2000.
Bonus: Luzerne County First lady Melania Trump was also heading to Wapwallopen in Luzerne County this evening -- one of three "pivot" counties that went for Trump four years ago after backing Obama twice.

Biden tests negative for COVID-19 Saturday
Former Vice President Joe Biden tested negative for COVID-19 on Saturday, according to the pool.
This was his 18th negative test announced since Trump's positive diagnosis earlier this month.
Former President Barack Obama and Vice President Joe Biden are campaigning in Detroit and Flint, Michigan, Saturday in their first in-person appearance together on the 2020 campaign trail.
At the first event in Flint, Obama removed his “VOTE” mask to tell the drive-in crowd, “this Tuesday, everything is on the line.”
“Our jobs are on the line, our health care is on the line,” Obama said.
Obama bashed President Trump's response to the pandemic, saying, "If Trump were focused on COVID from the beginning, cases wouldn't be reaching new record highs."
"Trump cares about feeding his ego," the former president said.
"Joe's not going to call scientists idiots," Obama said. "He's not going to host super-spreader events."
"Tweeting at the TV doesn't fix things," Obama said, but "Biden has concrete plans."
"Joe's plan will guarantee paid sick leave for workers and parents affected by the pandemic. He'll make sure the small businesses in every community ... can reopen safely," he said.
Biden then joined Obama, telling the crowd, "It's time for Donald Trump to pack his bags and go home. We're done with the chaos ... the failure, the refusal to take any responsibility."
"Imagine where we'd be if we had a president who wore a mask instead of mocking it," Biden said.
Both Detroit and Flint are Democratic strongholds. But in 2016, declines among some of the Democrats’ core constituencies helped Trump win Michigan by under 11,000 votes.
Hillary Clinton won both Wayne and Genesee counties, home to Detroit and Flint, but her margins were significantly less than Obama in 2012.
