The Epoch Times' Jack Phillips reports that the campaign, in a Thursday news conference, comes as Democratic presidential challenger Joe Biden has an approximately 8,000-vote lead over the president in Nevada. The state, which has 6 Electoral College votes, could be a key in the outcome of the presidential race.

Trump campaign Nevada chairman Adam Laxalt said there were "examples of ballots mailed across this valley … in trash cans… people getting as many as 18 ballots" in the mail, saying that it is evidence of voter irregularity.

"We still have not been able to observe these signatures or meaningfully examine mail-in ballots out of hundreds of thousands of ballots cast," Laxalt, the former Nevada attorney general, said in the news conference. He added there were "dead voters that have been counted."

Meanwhile, he claimed, "thousands of people who have been counted … have moved out of Clark County during the pandemic." Clark County includes Las Vegas, the state's largest city.

As a result, he said Trump's team is seeking emergency relief and is "stop the county of all these votes."

Ric Grenell, Trump's former acting director of national intelligence, told the conference:

"If you haven't been in the state for 30 days it is illegal to vote … we are filing this lawsuit to protect legal voters."

Clark County hasn't responded to a request for comment.
