The Federal Bureau of Investigation is likely to interview Hillary Clinton in the next few weeks about her use of a private email server while she was U.S. secretary of state and have already interviewed some of her aides, CNN reported on Thursday.
The nine-month investigation into whether laws were broken as a result of the server kept in her New York home has overshadowed Clinton's campaign to become the Democratic Party's candidate in November's presidential election.
With only a few states left to vote in primary elections, she retains a commanding lead over her rival, U.S. Sen. Bernie Sanders of Vermont.
