Officials with former President Donald Trump's re-election campaign, including Rudy Giuliani, oversaw efforts to submit illegitimate electors from Nevada and six other states that Trump lost, according to multiple reports.

CNN reported that members of the campaign team coordinated the process on a state-by-state level, while The Washington Post reported that the rival slates of electors were meant to act as leverage for then-Vice President Mike Pence to reject Joe Biden's electoral victory.

The Post says the U.S. House committee investigating the Jan. 6 insurrection has been focused on uncovering the origins of the rival slates.

Biden won Nevada by about 33,600 votes over Trump in the 2020 presidential election. Many Republicans, including Trump, alleged without basis there was widespread voter fraud.

In Nevada, several lawsuits were filed over these allegations, but all were rejected in one form or another. Nevada Secretary of State Barbara Cegavaske, a Republican, said in April that her office investigated claims submitted by the Nevada GOP but found no evidence to support any allegations of widespread fraud.

The Nevada GOP publicized electors casting what it called "electoral votes" for Trump on Dec. 14, 2020, the same day Nevada's actual electors cast their ballots for Biden for president and Kamala Harris for vice president with Cegavske.

In reality, both the U.S. code and Nevada state law require that electoral votes be accepted by the Secretary of State.

Only one criminal case related to the 2020 general election has been publically prosecuted in Nevada so far.

Donald Kirk Hartle, 55, of Las Vegas pleaded guilty last fall to a charge of voting more than once. Hartle previously claimed in media interviews that someone had taken a ballot from his late wife, Rosemarie Hartle, and submitted it in her name, a claim that was amplified by Republicans.
