Former national security adviser John Bolton was charged Thursday in a federal probe into the potential mishandling of classified information, according to a person familiar with the case. The investigation surfaced publicly in August when the FBI searched his Maryland home and Washington office for records he may have retained from government service. News of the charges broke as President Trump spoke with reporters in the Oval Office; he said he hadn't known about the indictment and criticized Bolton, calling him "a bad person" and "a bad guy."
