Dow Takes Major Hit Upon News of FBI Relaunching Clinton Email Probe

The Dow Jones Industrial Average took a massive hit upon the news that the FBI was looking into newly discovered Hillary Clinton emails from her private server.

According to CNBC, the Dow had been up by as much 72 points before taking a quick fall when news broke shortly after 1 p.m. ET about the probe.

FBI Director James Comey sent a letter to congressional leaders that, during an unrelated case, the bureau learned of the existence of emails pertinent to its initial investigation, CNBC reported.

The FBI is probing new emails related to Hillary Clinton, FBI Director James Comey said in a Friday letter.

"In previous congressional testimony, I referred to the fact that the Federal Bureau of Investigation (FBI) had completed its investigation of former Secretary Clinton's personal email server. Due to recent developments, I am writing to supplement my previous testimony," Comey wrote.

"In connection with an unrelated case, the FBI has learned of the existence of emails that appear to be 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," he added.

"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," Comey concluded.

Stocks turned negative after the report of the new probe. Many analysts have said that markets were pricing in a Clinton victory in November.
