A person familiar with the matter says the FBI is searching the Maryland home of John Bolton, who served in President Donald Trump’s first administration as national security adviser but later became critical of the president. The person wasn't authorized to discuss the investigation by name and spoke on condition of anonymity to The Associated Press. They say the search is part of an investigation into the handling of classified documents. Messages left with a spokesperson for Bolton and the White House weren't immediately returned. A lawyer who's represented Bolton had no immediate comment Friday.
