WASHINGTON (AP) — A Democratic colleague from Hillary Rodham Clinton's Senate days says the former secretary of state should fully explain her actions involving the use of a private, nongovernment email account while she was the country's top diplomat.

California Sen. Dianne Feinstein says she thinks that from "this point on, the silence is going to hurt her."

Clinton is considered the front-runner for the party's 2016 presidential nomination, but hasn't entered the race yet.

Feinstein tells NBC's "Meet the Press" that the former first lady and New York senator "needs to step up and come out and say exactly what the situation was."

Clinton says that she's turned over all relevant emails — totaling 55,000 pages — to the State Department for review.
