Donald Trump has been indicted by a Manhattan grand jury, a historic reckoning after years of investigations into his personal, political and business dealings and an abrupt jolt to his bid to retake the White House. The exact nature of the charges was unclear Friday because the indictment remained under seal, but they stem from payments made during the 2016 presidential campaign to silence claims of an extramarital sexual encounter. Prosecutors said they were working to coordinate Trump’s surrender, which could happen early next week.

They did not say whether they intended to seek prison time in the event of a conviction, a development that wouldn’t prevent Trump from seeking and assuming the presidency. The indictment, the first against a former U.S. president, injects a local district attorney’s office into the heart of a national presidential race and ushers in criminal proceedings in a city that the ex-president for decades called home.
