Donald Trump’s campaign cheered the news that the FBI is reviewing new emails related to the investigation into Hillary Clinton's private email server, an October surprise that could damage her White House bid.

“A great day in our campaign just got even better," Trump campaign manager Kellyanne Conway declared on Twitter. "FBI reviewing new emails in Clinton probe.”


Conway's tweet Friday came shortly after news broke that FBI Director James Comey had sent a letter to Congress informing lawmakers that the bureau had “learned of the existence of emails that appear to be pertinent to this investigation” from an unrelated case.

“I agreed that the FBI should take appropriate investigative steps designed to allow investigators to review these emails to determine whether they may contain classified information, as well as to assess their importance to our investigation,” he wrote, noting that he can neither “assess whether” the material will be significant nor guess how long it will take to complete.

In a follow-up post, Conway retweeted House Speaker Paul Ryan, writing that the GOP leader “captures well what these latest developments mean.”

In his own statement, Ryan said, “Yet again, Hillary Clinton has nobody but herself to blame” and signaled that the FBI’s decision, “long overdue, is the result of her reckless use of a private email server, and her refusal to be forthcoming with federal investigators.”
