One court ruling has sparked a fresh political fight over how Americans vote.

President Trump says Congress should act now. Supporters call it election security. Critics say it would make voting harder for some Americans.

WHAT HAPPENED

After the U.S. Supreme Court ruled that states may continue counting mail ballots that are postmarked by Election Day but arrive later under state law, President Donald Trump called on Congress to pass the SAVE AMERICA Act.

In a social media post, Trump said the bill should require all voters to show a photo ID, prove U.S. citizenship, and end most mail-in voting except for illness, disability, military service, or travel. He argued there is "only one reason" to oppose those changes: cheating.

The Supreme Court's 5-4 decision rejected a Republican-backed challenge to Mississippi's law allowing ballots mailed by Election Day to be counted if they arrive within five business days. Similar laws exist in about 30 states and Washington, D.C.

WHAT THE BILL WOULD DO

Require photo ID to vote.

• Require proof of U.S. citizenship.
• End most mail-in voting, with limited exceptions.
• Trump says the House has approved the proposal three times.
• The measure has not passed the Senate.

THE BIGGER QUESTION

The debate is no longer just about one court ruling. It is about where the country draws the line between making elections secure and making voting easy to access.

Supporters argue stricter rules help prevent fraud and strengthen public trust. Opponents say there is little evidence of widespread voter fraud and warn that tougher requirements could keep eligible citizens from voting.

WHAT HAPPENS NOW

The Supreme Court's ruling remains in effect, meaning states with postmark grace periods can continue using them unless Congress changes federal law.

The future of the SAVE AMERICA Act now depends on whether it can gain enough support in the Senate.

WHAT WE STILL DON'T KNOW

Will the Senate vote on the SAVE AMERICA Act?

• Could the bill receive enough bipartisan support to pass?
• Will more states change their voting laws after the Supreme Court ruling?
