Senator Lindsey Graham (R-S.C.) on Saturday voiced support for what he described as President Trump's ultimatum to Iran, urging the country to "choose wisely" as a reported deadline approaches.

Graham stated that Trump has given Iran 48 hours to reopen the Strait of Hormuz and agree to peace negotiations with the United States. The senator said he spoke with the president Saturday morning and expressed confidence in Trump's commitment to the ultimatum.

According to Graham's statement, he is "completely convinced" that Trump will use "overwhelming military force" if Iran does not comply with the demands. The senator did not provide additional details about the specific terms of the alleged ultimatum or its origins.

The Strait of Hormuz is a critical shipping lane through which approximately one-fifth of the world's oil passes. Any disruption to this waterway typically raises concerns about global energy supplies and maritime commerce.

Neither the White House nor Iranian officials immediately responded to requests for comment regarding Graham's statements about the ultimatum. The reported deadline and its implications for U.S.-Iran relations remain unclear pending official confirmation from the Trump administration.
