Hillary Clinton's interview with the FBI may signal that the Justice Department is nearing the end of its yearlong probe of her use of a private email server while secretary of state.
The controversy has hung over her White House bid and provided an angle of attack for Republican Donald Trump and other critics.
The Clinton campaign says the presumptive presidential nominee for the Democratic Party gave a voluntary interview for 3 1/2 hours Saturday at FBI headquarters in Washington. Spokespeople for the FBI and the Justice Department have declined to comment.
Clinton tells NBC's "Meet the Press" that she has no knowledge of any timeline for the review. She won't comment on whether officials gave her an indication that charges would not be filed.
