In both Michigan and Georgia, the Donald Trump campaign lost lawsuits in which they complained about electoral malpractice and filed cases. While several US networks have already declared Biden to have won Michigan, Trump is a small margin ahead in Georgia.
The Trump campaign had sought to stop the counting of absentee ballots in Michigan, while they alleged in Georgia that even improper ballots were counted.
In Nevada's populous Clark County, which includes Las Vegas, Donald Trump's allies have also alleged that there have been voting irregularities.
After counting about 84 percent of the votes until Friday morning (IST), in which Joe Biden has a clear lead over Donald Trump, Nevada is still lagging.
Judge Cynthia Stephens of the Michigan Court of Claims rejected Trump's lawsuit on Thursday, arguing that the Michigan Secretary of State is not involved in the local counting process. On Friday, formal order will be issued.
Democratic presidential candidate Joe Biden has been declared the winner in Michigan by multiple news networks.
Stephens said during the oral hearing that the relief that is being requested in substantial part is completely unavailable through the secretary of state.
"In addition, even if this relief was available, it was filed at 4 o'clock, as opposed to when this suit was announced yesterday morning and the count was beginning, at which point the count had largely continued, I am told," she said.
Judge James F Bass dismissed the lawsuit in Georgia. Bass said, "I deny the request and dismiss the petition."
In Pennsylvania and Nevada, the Trump campaign also filed lawsuits. It called for a recount of votes in Wisconsin, which was also declared to have gone to Joe Biden.
