* Tom Hamburger, Rosalind Helderman, and Ellen Nakashima report that the Democratic National Committee is taking its case to the courts:

The Democratic National Committee filed a multimillion-dollar lawsuit Friday against the Russian government, the Trump campaign and the WikiLeaks organization alleging a far-reaching conspiracy to disrupt the 2016 campaign and tilt the election to Donald Trump.

The complaint, filed in federal district court in Manhattan, alleges that top Trump campaign officials conspired with the Russian government and its military spy agency to hurt Democratic presidential nominee Hillary Clinton and help Trump by hacking the computer networks of the Democratic Party and disseminating stolen material found there.

Should be some interesting things that come out in discovery.

* David Weigel and John Wagner report that Chuck Schumer is getting in the 4/20 spirit:

The Senate’s top Democrat announced Friday that he is introducing legislation to decriminalize marijuana, the first time that a leader of either party in Congress has endorsed a rollback of one of the country’s oldest drug laws.

Senate Minority Leader Charles E. Schumer (D-N.Y.) in a statement called the move “simply the right thing to do.”

“The time has come to decriminalize marijuana,” Schumer said. “My thinking — as well as the general population’s views — on the issue has evolved, and so I believe there’s no better time than the present to get this done. It’s simply the right thing to do.”

This is the closest thing to an official endorsement of this position by the Democratic Party.
