Washington D.C., Oct. 29 : With trouble resurfacing for Hillary Clinton as her email controversy roared back to the forefront of the presidential campaign, the Democrat Presidential nominee took the developments under her stride and called on the FBI to release all the facts pertaining to the case immediately.

Yesterday, FBI Director James Comey told lawmakers the bureau is reviewing new emails related to her personal server, CNN reports.

This latest development, which has come 11 days before the election and nearly four months after Comey said he wouldn't recommend criminal charges because of Clinton's use of the server, is bound to needle her campaign yet again.

However, Clinton has strongly called on the FBI to release the "full and complete facts" about its review.

"Voting is underway, so the American people deserve to get the full and complete facts immediately," Clinton said at a brief news conference in Des Moines, Iowa, adding it was "imperative that the bureau explain this issue in question, whatever it is, without any delay."

She further asserted that she was "confident whatever (the emails) are will not change the conclusion reached in July.

Meanwhile, Republican nominee Donald Trump, whose campaign has been taking a hit in the past several weeks, seized on the issue.

"Hillary Clinton's corruption is on a scale we've never seen before. We must not let her take her criminal scheme into the Oval Office," Trump said at a rally in Manchester, New Hampshire.

In a letter to eight congressional committee chairmen Friday, Comey said investigators are examining newly discovered emails that "appear to be pertinent" to the email probe.

"In connection with an unrelated case, the FBI has learned of the existence of emails that appear pertinent to the investigation. I am writing to inform you that the investigative team briefed me on this yesterday, and I agreed that the FBI should take appropriate investigative steps designed to allow investigators to review these emails to determine whether they contain classified information, as well as to assess their importance to our investigation," the statement read.
