A group of 489 former national security leaders, including Paul Selva, a retired four-star general and the vice chairman of the Joint Chiefs of Staff under Trump, have endorsed Joe Biden for president.

The big picture: Among the names signing Thursday’s letter: Sean O'Keefe, a former Navy secretary for President George H.W. Bush; Richard Armitage, deputy secretary of state for President George W. Bush; and Admiral Steve Abbot (ret.) who also worked in the last Bush White House.

  • Biden has also gathered a steady stream of endorsements from high-profile Republicans, including Cindy McCain, the wife of late Sen. John McCain, the Republican Party's nominee in 2008.

What they are saying: "We are Republicans, Democrats, and Independents. We love our country. Unfortunately, we also fear for it," they write in their Biden endorsement letter.

  • "We believe that Joe Biden is, above all, a good man with a strong sense of right and wrong."

A Maryland man has been arrested and charged for allegedly threatening to kidnap and kill former Vice President Joe Biden and Sen. Kamala Harris (D-Calif.), according to a criminal complaint filed by the Secret Service Wednesday.

The big picture: Fears of potential political violence are running high with just two weeks until Election Day. Earlier this month, the FBI foiled an alleged militia plot to kidnap the Democratic governors of Michigan and Virginia.

A surprise offer from Vladimir Putin has the U.S. and Russia once again circling a potential pre-election nuclear deal.

The big picture: The last treaty constraining the U.S. and Russia, New START, is due to expire on Feb. 5, 2021, two weeks after the next U.S. presidential inauguration. For the first time since the height of the Cold War, the nuclear guardrails could come off.

The cliffhanger could be ... Georgia

It hasn't backed a Democrat for president since 1992, but Georgia's changing demographics may prove pivotal this year — not only to Trump v. Biden, but also to whether Democrats take control of the Senate.

Why it matters: If the fate of the Senate did hinge on Georgia, it might be January before we know the outcome. Meanwhile, voters' understanding of this power in the final days of the election could juice turnout enough to impact presidential results.
