Today’s highlight May 25, 2020: George Floyd, a Black man, died when a white Minneapolis police officer pressed his knee on Floyd’s neck for about 9 1/2 minutes while Floyd was handcuffed and pleading that he couldn’t breathe; Floyd’s death, captured on video by a bystander, would lead to worldwide protests, some of which turned violent, and a reexamination of racism and policing in the U.S. On this date 1787: The Constitutional Convention began at the Pennsylvania State House (Independence Hall) in Philadelphia after enough delegates had shown up for a quorum. 1935: Babe Ruth hit his last three career home runs — Nos. 712, 713 and 714 — for the Boston Braves in a game against the Pittsburgh Pirates. (The Pirates won, 11-7.)
