Mark Warner says the Iran strikes raise serious legal and constitutional concerns
Mark WarnerU.S. Senator for Virginia at the statement date.
Sen. Mark Warner, vice chairman of the Senate Select Committee on Intelligence, said in a February 28 statement that the decision to take the nation to war rests with Congress and that launching large-scale military operations without an imminent threat raises serious legal and constitutional concerns. He called for a congressional briefing, a clear legal justification and a defined end state.
“The Constitution is clear: the decision to take this nation to war rests with Congress, and launching large-scale military operations – particularly in the absence of an imminent threat to the United States – raises serious legal and constitutional concerns.”

Archived copy (opens in a new tab)Before the quotation
Warner's statement responds to Trump's announcement of wide-ranging strikes inside Iran, which he said extended to senior Iranian leadership and risked pulling the United States into another broad conflict in the Middle East.
After the quotation
Warner then wrote that Congress must be fully briefed and that the administration must come forward with a clear legal justification, a defined end state and a plan that avoids another costly and unnecessary war.
How this statement is classified
The label describes this statement's response within the context above.
Why this label?
The case asks about support for the war in Iran. Warner criticizes the strikes as launched without congressional authorization or an imminent threat, so we used Condemned. Mixed or conditional was the closest label because he also describes Iran's leadership as a sponsor of terrorism, but he says that does not relieve a president of acting within the law.
