The Supreme Court's conservative majority sounds skeptical of state laws that allow the counting of late-arriving mail ballots, a target of President Donald Trump. The court heard arguments Monday in a case from Mississippi that also could affect voters in 13 other states and the District of Columbia, which have grace periods for ballots cast by mail. An additional 15 states that have more forgiving deadlines for ballots from military and overseas voters also could be impacted. A ruling is expected by late June, early enough to govern the counting of ballots in the 2026 midterm congressional elections. The court challenge is part of Trump's broader attack on most mail balloting.

The U.S. Supreme Court is set to hear arguments over a Mississippi law that allows counting late-arriving mail ballots after Election Day. The high court on Monday will hear from Republicans and Libertarians who sued the state, arguing that federal Election Day statutes envision a single day for casting ballots, which would mean that grace periods for receiving mail ballots aren't allowed. The practice is a frequent target of President Donald Trump and allies who argue it delays vote tallies and leads to suspicions about the results, even though there is no evidence of fraud in late-arriving ballots. Grace periods for all mail ballots are allowed in 14 states, with an additional 15 granting extra time for military and overseas ballots to arrive.

Republicans have launched an unprecedented effort to hold the Senate floor and talk for days about a bill that they know won't pass — an attempt to capture public attention on legislation requiring stricter voter registration rules as President Donald Trump pressures Congress to act before November's midterm elections. The talkathon began Tuesday and could last a week or longer as Senate Majority Leader John Thune tries to navigate Trump's insistence on the issue and Democrats' united opposition. The legislation would require Americans to prove they are U.S. citizens before they register to vote and to show identification at the polls, among other new voting requirements.

In a rare bipartisan effort for a deeply divided Congress, the Senate has passed a broad bill to make U.S. housing more accessible and affordable. The bill passed on Thursday would reduce regulations, regulate corporate investors and expand how housing dollars can be used to build affordable homes and rentals. It now heads back to the House, which passed a separate version earlier this year. It is unclear whether President Donald Trump would sign it after declaring last weekend that he won't sign any new measures unless Congress passes legislation that would require voters to show proof of citizenship.
