Top Republicans in Congress swiftly rallied behind President Trump on Saturday after he ordered strikes on three Iranian nuclear sites, even as senior Democrats and some G.O.P. lawmakers condemned it as an unconstitutional move that could drag the United States into a broader war in the Middle East.
In separate statements, the leading Republicans in Congress, Speaker Mike Johnson and Senator John Thune of South Dakota, the majority leader, commended the military operation, calling it a necessary check on Iran’s ambitions of developing a nuclear weapon. Both men had been briefed on the military action before the strike was carried out, according to three people familiar with the matter who were not authorized to discuss it publicly.
