The FBI is aware of two fabricated news clips and press releases urging people not to vote and rigged inmate voting, according to a statement they released on Tuesday morning.
"The FBI was made aware of two instances of its name and insignia being misused in promoting false narratives surrounding the election," the FBI said in a statement. "The first is a fabricated newsclip purporting to be a terrorist warning issued by the FBI. The fabricated newsclip reports falsely that the FBI purportedly stated that Americans should 'vote remotely' due to a high terror threat at polling stations. This video is not authentic and does not accurately represent the current threat posture or polling location safety. Additionally, a fabricated video containing a fabricated FBI press release alleges that the management of five prisons in Pennsylvania, Georgia, and Arizona rigged inmate voting and colluded with a political party. This video is also not authentic, and its contents are false."
This is the second such warning the FBI has given in recent days.

The Department of Justice has agreed to keep its federal monitors from entering Texas polling locations on Election Day – a victory for Attorney General Ken Paxton who sued the department earlier.
According to the agreement, election monitors from DOJ will remain outside of polling and central count locations.
"Texans run Texas elections, and we will not be bullied by the Department of Justice," said Attorney General Paxton in a statement. "The DOJ knows it has no authority to monitor Texas elections and backed down when Texas stood up for the rule of law. No federal agent will be permitted to interfere with Texas's free and fair elections."

The Cybersecurity and Infrastructure Security Agency (CISA) is not tracking any "national level significant incidents" on election day, according to a top CISA official.
Cait Conley, a senior advisor to the CISA Director and the official in charge of election security said in the early hours of voting, there haven't been any major incidents.
"We are tracking instances of extreme weather and other temporary infrastructure disruptions in certain areas of the country, but these are largely expected, routine and planned for events separately," she said on a call with reporters on Tuesday.
Additionally, Conley told ABC News that they are "not aware" of any foreign influence operations going on right now but they "remain incredibly vigilant and in close communication with our federal government partners in case such instances were to arise."
Monday night, the intelligence community, including CISA attributed two Russian influence operations including one in Arizona that were spreading misinformation about the election.
