F.B.I. agents are searching the Maryland home of John Bolton, President Trump’s former national security adviser, said an F.B.I. official. Asked about the visible F.B.I. presence at Bolton’s home, a spokesperson for the bureau said agents were “conducting court-authorized activity in the area.” The investigation into Bolton seeks to determine whether he illegally shared or possessed classified information, according to two people familiar with the case who spoke on condition of anonymity to describe the thrust of the investigation. Similar accusations by the Trump administration years ago over Bolton’s book about his time in the White House failed to gain traction either with criminal investigators or the courts. A lawyer for Bolton did not immediately respond to messages seeking comment.
