News flash, they didn’t try to hide it on November 6, 2018, nor in 2016. Voter fraud was also used in early voting; count on it.

United States Attorney Brian J. Kuester concluded, “Ensuring free and fair elections depends in large part on the cooperation of the American electorate. It is imperative that those who have specific information about discrimination or election fraud make that information available immediately to this Office, the FBI, or the Civil Rights Division.”
That may be true, Brian, but "free and fair elections" depends in a larger part part on enforcement of election laws. That may well include your agency taking legal action against negligent or blatantly corrupt state election officials. Are you and your agency up for that and, if so, what does your record look like?
Much of the fraud that is occurring is not visible to the public. Nonetheless, start prosecuting such officials and the electorate will likely respond with an increasingly greater amount of cooperation.
