Former Secretary of State John Kerry endorsed Joe Biden in an interview with the Washington Post Thursday, adding that he will join the former vice president on the campaign trail beginning on Friday.

Why it matters: The endorsement isn't a surprise, but it comes from a former Democratic nominee for president and a respected figure within the party.

"The world is broken. Our politics are broken. The country faces extraordinary challenges. And I believe very deeply that Joe Biden’s character, his ability to persevere, his decency and the experiences that he brings to the table are critical to the moment. The world has to be put back together, the world that Donald Trump has smashed apart.”
— Kerry

FBI stats show border cities are among the safest

U.S. communities along the Mexico border are among the safest in America, with some border cities holding crime rates well below the national average, FBI statistics show.

Why it matters: The latest crime data collected by the FBI from 2019 contradicts the narrative by President Trump and others that the U.S.-Mexico border is a "lawless" region suffering from violence and mayhem.

The rise of military space powers

Nations around the world are shoring up their defensive and offensive capabilities in space — for today's wars and tomorrow's.

Why it matters: Using space as a warfighting domain opens up new avenues for technologically advanced nations to dominate their enemies. But it can also make those countries more vulnerable to attack in novel ways.
