Federal judges over the weekend blocked several last-minute Justice Department and allied election requests as Americans vote Tuesday, while the department asked the Supreme Court to require California to set aside about 20,000 ballots of suspected noncitizens^1,8.

States Newsroom outlets, republishing the same report, said a federal judge ordered the list of about 20,000 suspected noncitizens in California shared with an immigrant-rights group, which said Saturday it found major problems with the list^1,8. Another judge blocked the Justice Department from threatening election workers with prosecution, an Alaska judge dismissed a lawsuit that sought to question certification of the state’s U.S. Senate race, and an appeals court upheld limits on Homeland Security preelection field operations^1,2.

President Donald Trump and his supporters have said federal action is needed to stop noncitizen voting, which they say cancels out votes of U.S. citizens¹. The same report said researchers have found such voting rare and not outcome-changing, and that Homeland Security has arrested dozens of noncitizens on election-crime allegations in recent weeks².

Trump said at a rally in Salina, Kansas, on Sunday that senators who did not advance a proof-of-citizenship bill did so “so they can cheat,” according to the States Newsroom account^2,5. The SAVE America Act passed the House but did not advance in the Senate amid bipartisan opposition, the report said³.

CNBC, in a separate Election Day preview, said the administration’s months-long effort has included lawsuits, an attempt at a U.S. Postal Service rule for mail-in ballots, letters to state election officials and plans for more poll monitors, and that those efforts could continue after Tuesday²¹.

California Attorney General Rob Bonta told CNBC that he and other Democratic state attorneys general had planned for a range of scenarios and that each of the administration’s recent attempts had failed²¹. Bonta said California was prepared to seek court relief if National Guard, ICE or other armed presence appeared near polling places or if ballots were seized²¹.

The States Newsroom report said election forecasters had Democrats on track to win the House and possibly the Senate amid voter unhappiness with consumer costs, and that voting-rights groups and some former Trump officials expected possible disruptions³. What courts decide Monday and how any federal monitors operate at polling places remained unresolved in the accounts available^1,21.
