William Barr, Kentucky Derby, Met Gala: Your Weekend Briefing

Here are the week’s top stories, and a look ahead.

1. Attorney General William Barr has a deadline to meet Monday or else he may face contempt of Congress.

House Democrats want the Justice Department to hand over special counsel Robert Mueller’s full report and its underlying evidence, and gave Mr. Barr until tomorrow to do so. The threat came days after Mr. Barr had testified before the Senate Judiciary Committee, above, but had skipped a House hearing on the same topic.

President Trump has also vowed to resist all subpoenas. Here’s how it could all play out.

In other Trump administration news, North Korea fired a volley of projectiles off its east coast early Saturday morning in a move that analysts said was intended to escalate the pressure on Mr. Trump to return to the negotiating table.

2. House Speaker Nancy Pelosi is focusing on 2020.

The speaker’s plan for defeating President Trump, who she worries would challenge a slim Democratic victory in 2020, focuses on moderate voters and on avoiding a protracted impeachment bid. We sat down with her for an interview at the Capitol.

On the 2020 campaign trail, Joe Biden has focused on Mr. Trump as the source of the nation’s ills, exposing a rift with other Democrats who see the president as a symptom of something deeper.

Meanwhile Democrats are confronting a harsh reality: Top-tier candidates are refusing to run for the Senate, putting their chances of flipping the chamber at risk.

3. The worst is over in India as Cyclone Fani, one of the biggest storms in years, passed over the subcontinent.

The storm washed out countless homes and farms, but by Saturday evening local time, fewer than 20 deaths had been reported in India. Above, destruction in Puri, India. That’s because India and neighboring Bangladesh embarked on a massive evacuation, whisking more than a million people to safety in each country. It was a meticulous plan that they had been perfecting for 20 years.

4. In other international news:

Palestinian militants launched 250 rockets and mortars into Israel on Saturday killing an Israeli citizen, and Israel responded with airstrikes of their own, killing four Palestinians.

5. The 145th running of the Kentucky Derby ended in astonishment and controversy.

Country Horse, a 65-1 long shot, above, was named winner after an objection disqualified Maximum Security, who had crossed the finish line first but interfered with another horse. The stunning reversal came after 20 minutes of deliberation by the racing stewards.

The win gave Hall of Fame trainer Bill Mott an elusive Derby win.

“It was not a popular decision,” our sports reporter writes. “In fact, it was the brave one.”

6. How harsh a penalty does Facebook deserve for mishandling user data? The Federal Trade Commission can’t agree, and a fine may be lighter than some regulators want.

As the F.T.C. finalizes what could amount to a historic settlement (Facebook has said it set aside $3 billion to $5 billion to settle claims), its commissioners are divided over how big the appropriate financial penalty should be and the degree to which Mark Zuckerberg, above, should be held personally liable.

The case is considered a litmus test of how the U.S. government will police the country’s tech giants.

In other tech news, Uber doesn’t want its co-founder, Travis Kalanick, ringing the bell at its I.P.O. this week as it tries to show it’s evolved past its raucous early years.

7. Tomorrow is the first Monday in May. That might not mean very much to you, but for celebrities and fans, it marks the annual Met Gala.

Officially, the Metropolitan Museum of Art in New York hosts an extravaganza to raise money for the museum’s Costume Institute. Unofficially, it’s the party of the year. Our chief fashion critic breaks it all down, including how much it costs, who hosts and what guests are wearing. Above, Rihanna walks the red carpet at last year’s gala.

This year’s theme is camp, everything over the top. (Leave your hiking boots at home.) What is — and what is not — camp? Our Styles desk explains. Hint: John Waters and Cher make the list.

We’ll have a live updates as soon as the hosts make their entrance around 6 p.m.

9. On almost any other day, Stephanie Stein would have had a good chance of winning “Jeopardy!.” But then along came James Holzhauer.

The 22-time winner’s (through Friday) record-smashing run on the game show has turned him into a household name. Ms. Stein writes about what it’s like to go up against him.

“It’s supposed to be fun: you’re playing a game,” she writes. “But that morning, it felt like we’d stumbled into a war zone.”

10. Finally, dig into one of our Best Weekend Reads.

This week, Japan enthroned a new emperor, and our Tokyo bureau chief tells us in riveting detail how we got to this moment. We also have a story about South Korean grandmas enrolling in school to learn how to read and write, above, and Scrabble finally O.K.’d, “OK” (for six points).

For more suggestions on what to read, watch and listen to, check out these 10 new books our editors liked, the latest small-screen recommendations from Watching and our music critics’ latest playlist.

Have a winning week.
