National security officials endorse Biden

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."
