Election 2020 updates: Biden warns of 'dark winter,' pushes masks in pandemic plan

The Cybersecurity and Infrastructure Security Agency pushed back on claims there were counterfeit ballots.

The agency, a component of the Department of Homeland Security, did not mention Trump by name.

"Local election offices have security and detection measures in place that make it highly difficult to commit fraud through counterfeit ballots," the agency said on its rumor control page. "While the specific measures vary, in accordance with state and local election laws and practices, ballot security measures can include signature matching, information checks, barcodes, watermarks, and precise paper weights."

In a subsequent tweet,  Director Chris Krebs said there was disinformation floating around that CISA printed ballots, which is untrue.

The Trump campaign is expected to name adviser Dave Bossie to lead the campaign's legal efforts challenging the election results, sources confirmed to ABC News.
Bossie is the head of Citizens United -- a conservative nonprofit organization -- and was Trump's deputy campaign manager in 2016.

Judge Cynthia Stephens issued a formal order Friday denying the Trump campaign's request to stop counting in Wayne County, Michigan, home to Detroit.

Stephens specifically cited the lack of evidence and detail provided by the campaign in the case.

"As stated on the record at the November 5, 2020 hearing, plaintiffs are not entitled to the extraordinary form of emergency relief they have requested," she wrote.

The suit tried to stop the vote count in based on allegations that the campaign was not given adequate access to observe the vote counting process. It was also seeking access to review any ballots that were opened which they were unable to witness.

With Trump trailing Biden in the Pennsylvania vote count, state Republicans are asking the U.S. Supreme Court for an emergency order to ensure that no late-arriving mail ballots are added to the totals. 

Pennsylvania Secretary of State Kathy Boockvar has already confirmed to ABCNews that those ballots are not showing up in the tally. 

But in the attached filing, the GOP argues that Boockvar's guidance is non-biding on county boards and claims that 25 of 67 counties haven't indicated whether or not they are abiding by it and in fact segregating the late-arriving votes.

"Without an immediate order from this Court, [Republican Party of Pennsylvania] could lose its right to 'a targeted remedy' if the State Supreme Court’s decision is ultimately overturned," they write.
