Olympic champion Caster Semenya lost her appeal against the governing body of track and field's rule requiring female runners to lower their naturally high testosterone levels with medication, AP reports.

Why it matters: Semenya will not be able to attend the Tokyo Games next year to defend her 800-meter Olympic title nor any major meets in distances from 400 to 1,500 meters unless she lowers her testosterone level through surgery or medication, which she has said she won't do.

Joe Biden is calling for the winner of November's presidential election to select Ruth Bader Ginsburg's replacement on the Supreme Court.

What he's saying: "[L]et me be clear: The voters should pick the president and the president should pick the justice for the Senate to consider," Biden said. "This was the position the Republican Senate took in 2016 when there were almost 10 months to go before the election. That's the position the United States Senate must take today, and the election's only 46 days off.
