South Carolina Senator Lindsey Graham congratulated Trump and said he "made the right decision."

He adds that "the Iranian regime deserves it."

Republican Senator Roger Wicker echoes the praise, saying Trump made a "deliberate" and "correct" decision to eliminate the "existential threat" posed by Iran.

But there is also criticism from some, with Republican Senator Thomas Massie of Kentucky saying "this is not constitutional."

Sara Jacobs, a Democratic representative from California, says the attacks are "an escalation that risks leading the US into another endless and deadly war."

Secretary of State Marco Rubio retweeted Trump's announcement on Truth Social, but has yet to publicly comment on the attacks.
