The plan: To allow about 500,000 undocumented immigrants married to U.S. citizens to apply for legal residency without having to leave the country. Biden will announce it today.
It's a big move: Immigration is a key issue ahead of November's election. Biden's Republican rival, Donald Trump, has threatened to carry out mass deportations if elected.
Other policy news: The IRS said it would raise billions by closing a tax loophole for businesses and wealthy individuals.

Why? For talks with North Korean leader Kim Jong Un. It's a sign of the countries' growing cooperation as Russia seeks more weapons for its war in Ukraine.

How? Mark Robinson spent years questioning the credibility of women who made allegations against men like Harvey Weinstein and Bill Cosby, The Post reported today.
Why it matters: His remarks could make it more difficult for Republicans to flip a Democratic governorship in November. Find our review of his social media posts here.

The idea: To require platforms to add labels reminding users that social media has not been proved safe. U.S. Surgeon General Vivek Murthy called for Congress to act yesterday.
Why? It would help to combat a mental health emergency among teens, Murthy said. But there is no clear evidence social media causes mental health issues among young people.
