President Donald Trump has signed a contentious new executive order that could significantly impact future US elections, leading to heated discussions across the country.

Since taking office in January, the 78-year-old Republican president has issued nearly 100 executive orders, covering a wide range of issues—from renaming the Gulf of Mexico to the Gulf of America to dismantling the Department of Education. However, his most recent order,

signed on Tuesday, is drawing particular attention. The order, titled Preserving and Protecting the Integrity of American Elections, mandates that voters provide proof of US citizenship when registering to vote in federal elections, a move critics argue could disenfranchise millions.
