And they had better not get it.
It would be a clear violation of the Hatch Act for the FBI to disclose any of that information a week before the election to Members of Congress who will simply post it on the Internet for political purposes. And nobody cares if the FBI director or anyone else at the FBI promised House or Senate Democrats that he would keep them "fully informed" about any open or closed investigations concerning Donald Trump. Such a promise should never be made to begin with.
We use agencies such as the FBI, the Secret Service and the CIA to enforce the law and to protect our national security, not to investigate our political opponents for the purpose of winning elections. Even a cause as compelling as preventing foreign meddling in our elections does not justify such an abuse of power.
