Members of Congress across both parties are reacting to the United States’ overnight military strikes on three of Iran’s most fortified nuclear facilities — Fordow, Natanz, and Isfahan — with a mix of support, caution, and urgent calls for diplomatic restraint.

President Donald Trump authorized the precision strikes late Friday, calling them a “spectacular military success.” While administration officials have framed the operation as a warning to Tehran over its continued uranium enrichment, many lawmakers emphasized the risk of broader regional escalation.

Sen. Lindsey Graham (R-SC) called the strikes “a grave but necessary step,” adding that the U.S. must “show Iran there are limits to its nuclear ambitions.”

Sen. Chris Murphy (D-CT), a member of the Senate Foreign Relations Committee, warned that the administration is “playing with fire,” saying Congress must be involved in any path toward extended military conflict.

Rep. Ilhan Omar (D-MN) condemned the operation outright, tweeting that “this reckless use of military force only escalates tensions and endangers millions of lives.”

On the Republican side, most lawmakers expressed support for the operation, praising Trump’s decisive action in the face of what the administration described as "undeniable evidence" of Iran nearing weapons-grade enrichment.

“Iran has played a dangerous game for years. We should’ve hit these sites long ago,” said Rep. Mike Turner (R-OH).

Meanwhile, Senate Majority Leader Mitch McConnell urged unity, stating: “Now is the time to show strength abroad and stability at home.”

Several lawmakers called on the administration to brief Congress immediately. Closed-door sessions with Pentagon and intelligence officials are expected early this week, with both chambers seeking clarity on the long-term strategy for Iran.

The Pentagon maintains that the operation was limited in scope and designed to avoid civilian casualties, though fallout across the Middle East — particularly from Iran-backed militias — remains a significant concern.

With global markets rattled and diplomatic channels now in overdrive, lawmakers on Capitol Hill are bracing for what could become the most consequential foreign policy crisis of the year.
