It might be time for damage control. Democratic presidential nominee Hillary Clinton is set to hold a rally in Cedar Rapids, Iowa Friday. The rally was expected to commence shortly after the bombshell news broke that the FBI was looking into newly discovered emails that may be significant to the investigation into the former secretary of state's use of a private email server.

The FBI previously found no reason to charge Clinton with a crime. FBI Director James Comey sent a letter to Congress letting them know the bureau was reviewing emails that were found in an investigation for a separate case.

"Although the FBI cannot yet assess whether or not this material may be significant, and I cannot predict how long it will take us to complete this additional work, I believe it is important to update your committees about our efforts in light of my previous testimony," wrote Comey.

As it stands, we know very little about what the content of the newly found emails. Republican leadership, however, was quick to criticize Clinton, including GOP nominee Donald Trump, who held a rally of his own Friday in Manchester, New Hampshire.

Amid chants of his voters yelling "lock her up," Trump said "This is bigger than Watergate."

“Hillary Clinton’s corruption is on a scale we have never seen before,” Trump said. “We must not let her take her criminal scheme into the Oval Office.”

Speaker of the House Paul Ryan, a Republican, renewed his call for Clinton to not receive classified briefings until the issue was resolved. "This decision, long overdue, is a result of her reckless use of a private email server, and her refusal to be forthcoming with federal investigators," Ryan said in a statement.

In Comey's initial July statement that announced the FBI would not charge Clinton, he said that while investigators did not find a "case that would support bringing criminal charges," the former secretary of state's actions were "extremely careless."
