The US Secret Service will begin protecting the immediate family of President-elect Donald Trump in the coming days as the Biden and Trump administrations go through a transition period in the coming months, according to a law enforcement official. Mr. Trump's near-assassination in Butler, Pennsylvania, this summer, followed by a second alleged assassination attempt against him in Florida in September, prompted the Secret Service to step up its protection efforts. Agents have been pulled from investigative missions to help fill in gaps in the details of protection, an issue that could ease as Mr. Trump's campaign tour across the country draws to a close.
