U.S. First Lady Jill Biden arrived in Paris on Thursday ahead of the start of the Olympic Games. Heads of state and celebrities were arriving in the French capital ahead of the opening ceremony which is set to take place on Friday. The first Games with nearly equal numbers of men and women, an advance that's been a long time coming since 22 women first got accepted as Olympians 124 years ago, also in Paris, will take another step toward aligning the Olympics with the post-#MeToo world.
