Democrat Joe Biden is just 17 Electoral College votes shy of clinching a win for the White House, according to NBC News projections.”We know these [election] rolls were unclean” before Election Day, Laxalt said at a press conference in Las Vegas.”We firmly believe that there are ….voters in this group of mail-ins people who are not proper voters,” Laxalt said.”We believe there are dead voters that have been counted,” he said.”We are also confident that there are thousands of people who have been counted who moved out of Clark County [Nevada] during the pandemic.”Appearing with Laxalt at the event were Trump’s former acting Director of National Intelligence Ric Grenell, and American Conservative Union Chairman Matt Schlapp.Grenell tweeted Thursday morning: “Recklessly throwing ballots in the mail means illegal votes come back. Non-residents and dead people have voted. Democrats planned this. It’s an attack on our Democracy. We must only count LEGAL votes.”Laxalt during an interview Wednesday on Fox News’ “Tucker Carlson Tonight,” claimed that, “There is no question that Donald Trump would have won Nevada last night convincingly if we did not move to mail-in ballots.””We don’t know how [many] bad voters there are in this giant stack [of mail-in ballots] We also know there are likely to be dead voters. There are likely to be people that have moved out of Las Vegas but found their ballots were still cast,” Laxalt said. “So we’re looking into all of this.”Trump on Thursday morning tweeted a link to a Breitbart.com article detailing Laxalt’s comments to Carlson.Michigan and Wisconsin were called for Biden on Wednesday by NBC News. The Trump campaign has requested a recount in Wisconsin.Biden is gaining votes on Trump in counts in Georgia and Pennsylvania, two other battleground states that have yet to be called. Biden is also ahead in Arizona, which has 11 Electoral College votes.To win the Electoral College count, a candidate must have 270 votes.
