WASHINGTON (AP) — Republicans aren't letting up on their criticism of Hillary Clinton following the FBI's recommendation that she shouldn't face criminal charges over her handling of classified emails. Instead they're expanding their criticism to include the FBI itself.

The agency is supposed to be insulated from partisanship, with directors appointed to serve 10-year terms.

But Director James Comey's declaration that "no charges are appropriate" against Clinton drew a deluge of GOP criticism Tuesday.

House Speaker Paul Ryan of Wisconsin says Comey's recommendation that Clinton should not face prosecution "defies explanation," and "will set a terrible precedent."

Rep. Mike Turner of Ohio charged that "the investigation by the FBI is steeped in political bias," and called for appointment of an independent counsel in the case.
