Trump prepares to speak to journalists in Manhattan after a jury convicted him of felony crimes in a scheme to illegally influence the 2016 election. (Seth Wenig/Pool/AP) What to know: Twelve jurors returned a unanimous judgment yesterday, finding Trump guilty on all 34 felony charges of falsifying business records. We broke down the evidence here. It’s historic: Trump is the first former U.S. president convicted of a crime. After the verdict, he blasted the trial and said the “real verdict” will be Nov. 5 — Election Day. Read this story            Trump’s sentencing was set for July 11. What will happen? He faces a maximum sentence of four years in prison. But, given his age and lack of prior convictions, prison time appears unlikely. The timing: The Republican National Convention starts July 15 — just four days later. That’s where Trump is set to be formally nominated for president. Can he still be president? Yes. There’s nothing in the Constitution to stop him — even if he’s jailed. But, if elected, he wouldn’t be able to pardon himself.

What to know: The Direct File website is here to stay, the Biden administration announced yesterday. It was used by 140,000 taxpayers in 12 eligible states this tax season. Not everyone’s happy: Some Republican-led states signaled they might not participate in the service, which allows taxpayers to submit simple returns directly to the government.

How? The groups used artificial intelligence to write posts, translate them and build software to help spread them. Campaigns like this are a growing concern ahead of Election Day. Other AI news: Google is scaling back the use of AI-generated answers in some search results after errors — including telling users to put glue on their pizza. (Please don’t do that.)

What it means: The sun region that delivered this month’s once-in-a-generation geomagnetic storm — and magnificent auroras — is about to point toward Earth again. Miss the last auroras? You may get another shot starting tonight. The sunspot cluster is smaller, but it’s still hurling magnetic energy into space.

(Matt McClain/The Washington Post) Who? Bruhat Soma, a 12-year-old from Florida who loves basketball. He’ll receive $50,000 in cash, a commemorative medal and the Scripps Cup. It was a thriller: The contest ended in a spell-off for only the second time in history. Bruhat spelled a stunning 29 words correctly in just 90 seconds. Read this story
