Election security updates: FBI says election bomb threats appear to be from Russia

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.

The FBI is monitoring criminal threats to election workers and infrastructure from a 24/7 command post set up to ensure the election is safe and secure.

The command post, which is staffed with 80 people from more than a dozen agencies, will continue to operate for at least nine days.

"This command post is an opportunity for us to bring people together, all the different subject matter experts here in the FBI at headquarters and in the field, and we bring in our partners so the intelligence and threats that come in, and we can disseminate that information to the key partners, which is state and local officials around the United States," said Jim Barnacle, deputy assistant director of the FBI's Criminal Investigative Division.

The FBI is focused on criminal threats, such as threats to election workers, foreign malign influence, cyberthreats and acts of violence.

As millions of Americans descend on polling locations across the country, election officials and law enforcement authorities are focused on administering a fair and safe election under a cloud of threats, online disinformation, and the potential for a grueling legal fight in the weeks ahead.

Although a typical Election Day inevitably includes some hiccups like long lines or weather-related issues, this year election workers face the additional challenge of a heightened threat environment and an onslaught of litigation concerning voting rules and ballot counting.

Even so, election officials on Monday expressed confidence in their ability to execute on Election Day. Pennsylvania Secretary of State Al Schmidt said the vote in his state would be "free, fair, safe, and secure." Georgia Secretary of State Brad Raffensperger said that "at the end of the day, it's going to be fair and fast and accurate."

And in North Carolina, Karen Brinson Bell, the executive director of the state's Board of Elections, said, "Despite all the naysayers, despite all false information and sensationalist rhetoric out there about elections, and despite a devastating hurricane, we are making this happen in North Carolina."
