LAS VEGAS, Nevada – A second sworn affidavit from a whistleblower who was an election worker in Clark County, Nevada, claims mail-in ballots were improperly filled out in a Biden-Harris van outside a polling place.

A redacted copy of the affidavit signed on Nov. 8 and obtained by the Washington Examiner puts weight behind some of the claims first detailed by American Conservative Union President Matt Schlapp, who is helping lead the charge for the president’s legal efforts in Nevada. In a Sunday press conference, Schlapp said that an election worker saw a van “marked Biden-Harris” with open ballots inside.

The whistleblower, who worked as a poll worker from Oct. 17-30, complained about a Biden-Harris bus or van that was often stationed outside the polling place that would often have “speakers, dancers, music and other festivities going on” and whose organizers had to be told “several times a day” to “stay 100 feet from the polling location.” He also said that voters without proper identification were permitted to cast provisional ballots.

The biggest shock claim, though, dealt with improperly filled out ballots in the van belonging to supporters of presumptive President-elect Joe Biden, whom he saw while on a lunch break walk on Oct. 28 or 29.

“I personally witnessed two people handing multiple unopened mail in ballot envelopes to two other people who then opened and filled out the ballots against the side of the Biden/Harris van,” the affidavit said. “The same two people who marked the ballots then put the marked ballots in official pink and white envelopes. These people were not poll workers."

The affidavit continued: "By my final walking lap, there were 5 or 6 additional people who formed a human wall, which moved as I walked by, apparently in an attempt to block my view of the four people who were opening envelopes, marking ballots, and placing those ballots in the pink and white return envelopes.”

The whistleblower recalled reporting the incident to a supervisor, who then called the Clark County Elections Office, to no avail.

“Someone there told her nothing could be done about the ballots or envelopes being handled outside at the Biden/Harris area,” the whistleblower said in the affidavit. The elections office added that “ballot harvesting is legal in Nevada,” according to the affidavit, but that practice is not what the whistleblower detailed.

“Ballot harvesting” is when a person collects and returns already-completed ballots. People not operating in a government capacity are not legally allowed to distribute mail-in ballots or mark ballots for others.

Another Clark County, Nevada, whistleblower who worked in a ballot-counting center has signed an affidavit claiming that a supervisor instructed the person to process mail-in ballots despite concerns about whether the signature matched the name on the envelope.

President Trump lags about 36,200 votes behind Biden in Nevada.
