The latest developments:

●  Joe Biden just took the lead in Pennsylvania, a state Trump needs in order to win reelection.

●  Biden is also leading in Georgia, Nevada and Arizona.

●  Six states remain too close to call.

●  New restricted “national defense airspace” has been put in place over Democratic nominee Joe Biden’s home in Wilmington, Delaware.

Trump doesn’t have a path forward without Pennsylvania

Democratic nominee Joe Biden just took the lead in Pennsylvania over President Trump, where 95% of the vote count has been reported.

Here’s why this matters: Trump cannot find a route to 270 electoral votes without Pennsylvania’s 20 electoral votes, so his chances of securing reelection will hinge on developments in the states.

Right now, Biden has 253 electoral votes. If he wins Pennsylvania, he’s over the 270 electoral vote threshold.

And remember: Five more states — Alaska, Arizona, Georgia, Nevada and North Carolina – are still yet to be projected. Trump has leads in Alaska and North Carolina, while Biden has leads in Arizona, Georgia and Nevada.

In conversations with allies in recent days, President Trump has said he has no intention to concede the election to Joe Biden, even if his path to a second term in office is effectively blocked by losses in places like Georgia and Pennsylvania.

Aides, including his chief of staff Mark Meadows, have not attempted to bring Trump to terms of what’s happening and have instead fed his baseless claim that the election is being stolen from him.

Trump’s allies have grown concerned that someone is going to have to reckon with the President that his time in office is potentially coming to an end, though they have not decided who should be the one to do it. There has been talk of potentially Jared Kushner or Ivanka Trump doing so, sources said.

John King: Biden taking lead over Trump in Pennsylvania is “potentially decisive moment in the race”

From CNN's Adrienne Vogt

Joe Biden has taken the lead in Pennsylvania over President Trump, a “dramatic and potentially decisive” development, CNN’s John King said.

In the latest update, Biden got 27,396 votes, while Trump got 3,760 votes. Of the 31,412 votes that were just tallied, 87% of that vote came in for Biden. He has now taken the lead in Pennsylvania by 5,587 votes.

Overall in the state, Biden has 3,295,304 votes, 49.4% of the total — while Trump has 3,289,717 votes, or 49.3%.

“The President cannot win reelection without Pennsylvania and without Georgia. Overnight, Georgia flipped blue. Seconds ago, Pennsylvania flipped to the blue. We cannot understate this moment. It’s not over, still counting votes, but Joe Biden now in the lead in Pennsylvania, in the lead in Georgia, in the lead in Nevada, in the lead in Arizona,” King said.

“Bombastic statements” won’t help Trump in possible recount and contest proceedings, GOP election lawyer says

From CNN's Aditi Sangal

President Trump’s series of lawsuits in multiple states and baseless claims of widespread electoral fraud are not enough to throw the election result in doubt, Republican election lawyer Ben Ginsberg says.

“The credible path is to actually be able to produce evidence in the individual states to show fraud to throw the results in doubt,” Ginsberg said Friday. “Bombastic statements do not work in the recount and contest proceedings in states.”

More on evidence, he said:

“If you haven’t developed the evidence on Election Day in real time, you’re not going to be able to mount it and collect it afterwards,” he added. “There will be all sorts of legal conspiracy theories, but the President doesn’t have many options absent real evidence.”

Secret Service sends more agents to Delaware in anticipation of a potential Biden win

More US Secret Service agents have been sent to Wilmington, Delaware, in anticipation of a potential Joe Biden presidential win, CNN has learned.

The extra Secret Service agents were sent to Delaware Thursday, two sources said, with one law enforcement source telling CNN, “This was anticipated.” 

Some context: Upon a presidential win, the USSS detail for a president-elect would get larger and mirror the size and scope of a president’s. Additional airspace security measures are also implemented, a source familiar with USSS protocols said. A team for Biden has been on standby since last week, the source said.

“This is as expected. It’s actually a little bit delayed. It’s not telegraphing any specific concern,” a senior law enforcement official said. The bolstering of security typically happens on election night, the official said, but USSS has played it “cautiously” as the agency does not want seen as making a decision on the election.

On Wednesday, CNN observed additional security assets in Biden’s motorcade consistent with Presidential entourages that are equipped to handle a wide variety of threats and situations and are not part of the typical secret service teams a candidate receives, in addition to Biden’s original detail.

A USSS spokesperson declined to provide additional details, telling CNN, “For operational security reasons, the Secret Service cannot discuss specifically or in general terms the means, methods or resources we utilize to carry out our protective mission.”
