The federal case against Donald Trump in South Florida became more complex Thursday night and threw a new wrinkle into the 2024 presidential campaign calendar as the former president prepares for a high-profile criminal trial just two months before he hopes to accept the Republican nomination in Milwaukee.

Prosecutors filed a superseding indictment that adds new charges and a new defendant to Trump’s case, but even so Special Counsel Jack Smith’s office said in a Thursday night filing that it should not delay the mid-May start date that’s already been set for the trial in Fort Pierce, Fla.

“The superseding indictment should not disturb the Court’s scheduling order,” prosecutors wrote, “or the May 20, 2024 trial date, and the Special Counsel’s Office is taking steps related to discovery and security clearances to ensure that it does not do so.”
