Trump's campaign is asking the U.S. Supreme Court to declare that Wisconsin's election failed and allow the Republican-controlled Legislature to appoint the state's electors.

U.S. President Donald Trump hosted several House Republican lawmakers at the White House on Monday.

The court's order was its second this week rebuffing Republican requests that it get involved in the 2020 election outcome.

The court without comment refused to call into question the the certification process in Pennsylvania.

Similar lawsuits have been dismissed by courts in other parts of the country.

"The problem is it's hard to get it to the Supreme Court," Trump said in a telephone interview with Fox News.

The justices split 5-4, with new Justice Amy Coney Barrett in the majority, her first publicly discernible vote as a justice.

It's not clear what legal issues might cause the justices to step in, while Chief Justice John Roberts is not likely to want the election to come down to the high court.

Twitter hid Trump's tweet behind a notice saying "some or all" of its content "is disputed and might be misleading about an election or other civic process."

The two cases Barrett will hear Monday are relatively low-profile, a dispute involving the Freedom of Information Act and another involving disability benefits for railroad employees.
