Skimm This: Sanctuary Cities, Spread of HIV, Kentucky Derby Horses

It’s May 3rd. Today, we Skimm’d This:

• The Governor of Florida is about to sign a bill banning ‘sanctuary cities’ in Florida. We’ll explain what that means and how it lines up with the debate over undocumented immigrants in the US.

• A new long-term study of gay men with HIV who were taking anti-retroviral drugs found zero instances of them passing it to their partners. We’ll explain why this is a huge step closer to ending the AIDS epidemic.

• Today, the US government released the April jobs report. Turns out a lot more people updated their LinkedIn and cashed more checks last month than expected.

• And finally: get out your big hat, pour a julep and start checking your bets. The Kentucky Derby is tomorrow. Blink and you’ll miss it.

theSkimm: Florida’s governor is set to sign a bill telling counties and towns they can’t offer sanctuary to undocumented immigrants.

Also on today’s episode: a new jobs report that’ll make your wallet feel full, and fun horse facts when you go Eliza Doolittle this weekend.
