MADISON, Wis. (AP) — With time running out, and on the heels of a stinging defeat in the U.S. Supreme Court, President Donald Trump's attorneys turned their attention to Wisconsin with rare Saturday arguments before the state Supreme Court.

Trump is trying to overturn his loss to Democrat Joe Biden in the state with a lawsuit seeking to disqualify more than 221,000 votes in Wisconsin's two most heavily Democratic counties. Trump is not challenging any votes in counties he won.

Also Saturday, former Trump campaign attorney Sidney Powell asked the U.S. Supreme Court to hear a federal case she lost in Wisconsin seeking to order the GOP-controlled Legislature to declare Trump the winner. Powell has also lost similar cases in Georgia and Arizona.

Wisconsin's highest court agreed to take the case at Trump's urgent request Friday, soon after a state judge ruled against him and with Monday's Electoral College vote bearing down and the state's 10 electoral votes about to go to Biden.

The court is controlled 4-3 by conservatives, but its willingness to take the case isn't necessarily an indicator of how it will rule. The court previously refused to hear the case before it went through lower courts, and a majority of justices have openly questioned whether the remedy Trump seeks is appropriate.

Trump sought to have more than 221,000 ballots disqualified in Dane and Milwaukee counties. He wanted to disqualify absentee ballots cast early and in-person, saying there wasn’t a proper written request made for the ballots; absentee ballots cast by people who claimed “indefinitely confined” status; absentee ballots collected by poll workers at Madison parks; and absentee ballots where clerks filled in missing information on ballot envelopes.

The circuit judge on Friday ruled that none of Trump’s arguments had merit and that state law was followed during the election and subsequent recount.

Biden won Wisconsin by about 20,600 votes, a margin of 0.6% that withstood a Trump-requested recount in Milwaukee and Dane counties.

Trump and his allies have suffered dozens of defeats in Wisconsin and across the country in lawsuits that rely on unsubstantiated claims of widespread fraud and election abuse. On Friday evening, the U.S. Supreme Court rejected a Texas lawsuit that sought to invalidate Biden’s win by throwing out millions of votes in four battleground states, including Wisconsin.

A Trump-appointed federal judge in Wisconsin said Thursday that the president’s lawsuit was “incredible,” “bizarre” and “very odd,” and that overturning the results would be “the most remarkable ruling in the history of this court or the federal judiciary.”

U.S. District Judge Brett Ludwig’s ruling was pending.
