WASHINGTON (AP) — Hillary Clinton says she has been eager to have her interview with the FBI about her handling of email. The FBI interviewed her for 3 1/2 hours Saturday about her use of a private email server while she was secretary of state.

Clinton says in an interview with NBC’s “Meet the Press” that she is pleased to have the opportunity to assist the department bringing its review to a conclusion. She says the tone of the FBI session was civil and business-like.

Clinton says she has no knowledge of any timeline for the review and will not comment on whether she was given an indication that charges would not be filed.

For Clinton, the interview indicates that the Justice Department’s yearlong probe is drawing to a close only four weeks before she is set to be formally nominated as the Democrats’ choice to succeed President Barack Obama.

The interview with NBC’s Chuck Todd was conducted Saturday and will be aired Sunday.

Meanwhile, Donald Trump is weighing in.

In a tweet posted Saturday, Trump says “it is impossible for the FBI not to recommend criminal charges against Hillary Clinton. What she did was wrong!”
