Joe Biden tweeted his condolences to President Trump on Sunday, a day after the White House announced that his brother, Robert Trump, had died at 71.

Why it matters: Biden's experience losing his first wife and daughter in a car accident in 1972, as well as his son Beau in 2015, have helped shape his political persona. The president said of Robert Trump in a statement on Saturday: "He was not just my brother, he was my best friend. He will be greatly missed, but we will meet again."

What they're saying: "Mr. President, Jill and I are sad to learn of your younger brother Robert’s passing. I know the tremendous pain of losing a loved one — and I know how important family is in moments like these. I hope you know that our prayers are with you all," Biden wrote in a tweet.

  • Biden's running mate Kamala Harris added: "Doug and I join the Biden family in sending our deepest condolences and prayers to the entire Trump family during this difficult time. Losing a loved one is never easy but know that we are thinking of you."

Worth your time: In June, the New York Times, which described Biden as an "emissary of grief," reviewed nearly 60 eulogies that he had given throughout his career, offering "an intimate window into how he sought to comfort those joining him in mourning, and how he would seek to lead a nation grappling with death and devastation."

Democratic presidential nominee Joe Biden told reporters in Delaware Wednesday he believes he would have the legal authority as president to issue a nationwide mandate to wear face masks to curb the spread of the coronavirus if needed.

Details: "Our legal team thinks I can do that, based upon the degree to which there's a crisis in those states, and how bad things are for the country," Biden said.

When he talks about Russia, Joe Biden has sounded like Ronald Reagan all summer, setting up a potential Day 1 confrontation with Russian President Vladimir Putin if Biden were to win.

Why it matters: Biden has promised a forceful response against Russia for both election interference and alleged bounty payments to target American troops in Afghanistan. But being tougher than President Trump could be the easy part. The risk is overdoing it and making diplomacy impossible.

Mike Bloomberg's $100 million Florida blitz begins today and will continue "wall to wall" in all 10 TV markets through Election Day, advisers tell me.

Why it matters: Bloomberg thinks that Joe Biden putting away Florida is the most feasible way to head off the national chaos we could have if the outcome of Trump v. Biden remained uncertain long after Election Day.
