 Live from NPR News in Washington, I'm Dave Mattingly. President Biden is describing yesterday's U.S. Supreme Court ruling on presidential immunity as a dangerous precedent. In a 6-3 decision, the nation's high court said presidents are immune from prosecution for official acts carried out while in the White House. The court said unofficial acts have no such immunity. NPR's Giles Snyder says the ruling is seen as beneficial to former President Donald Trump.
