Republican Rep. Thomas Massie was among the first to criticize the attack on social media, writing plainly that he's against the war and that it does not reflect the president's "America First" promises. He pledged to again work with frequent collaborator California Democratic Rep. Ro Khanna on a war powers vote.

The U.S. is attacking Iran according to AP.https://t.co/Bgwk8yIdRT
GOP Sen. Rand Paul quoted Jon Quincy Adams, saying America "goes not abroad, in search of monsters to destroy" — adding that he "must oppose another Presidential war."
In the wake of the recent uprising in Iran, Paul had said, "There is the sticking point of the Constitution that we don't let president's bomb countries just when they feel like it. They're supposed to ask the people through the Congress for permission."
Rep. Morgan McGarvey, the only Kentucky Democrat on the hill, also pushed for a War Powers Resolution.
In a statement, Sen. Mitch McConnell briefly touched on Iran's repression at home and support for terrorism abroad but stopped short of declaring his support or opposition regarding the attacks themselves.
The Ayatollah of Iran maimed and killed countless American military members over the last 40+ years. President Trump’s bold leadership delivers justice for our fallen heroes and paves the way for historic change in Iran. https://t.co/tleedVtrrv

Republican Congressman Andy Barr voiced full support for the Iran attack, claiming the U.S. gave Iran "every chance to give up their nuclear ambitions." That's despite Trump's decision to withdraw the U.S. from the nuclear deal brokered during the Obama administration.
