Maine’s congressional delegates responded with words of caution, criticism and praise to President Donald Trump authorizing the U.S. to strike three Iranian nuclear sites, inserting the country alongside Israel in its 10-day war with Iran without congressional authorization.

Early Sunday, the U.S. dropped 30,000-pound bombs on a uranium enrichment site buried under a mountain in an effort to destroy Iran’s nuclear program, also firing dozens of missiles. As the attack prompted fears of wider and extended conflict, Republican Sen. Susan Collins called the strike “necessary.”

“The precision strike that the President ordered was a necessary response to Iran’s aggressive pursuit of nuclear weapons. This limited and decisive action is far preferable to the much broader conflict that would be all but inevitable if Iran were to obtain nuclear weapons,” Collins said in a written statement.

“A nuclear-armed Iran poses an existential threat to our ally Israel. Ultimately, as Iran continues to develop the capacity of its ballistic missiles, our country is also in danger,” she said.

Rep. Chellie Pingree, D-1st District, called the bombing “reckless” and “unconstitutional.”

“The President’s decision to bomb Iran without the authorization of Congress is reckless, unconstitutional, and puts countless lives at risk—including U.S. troops currently stationed in the Middle East,” Pingree said in a written statement.

“No President has the authority to launch a military attack against any country without Congressional authorization — especially when there’s no imminent threat to the American people. This is unconstitutional,” she added.

Pingree urged Congress to pass the War Powers Act, officially known as the War Powers Resolution, which requires that, in the absence of a declaration of war, that the president notify Congress within 48 hours of military action and limit deployments to 60 or 90 days unless otherwise authorized.

“It is imperative that Congress convene as soon as possible to address this crisis, to vote on the bipartisan War Powers Act introduced last week, and to make clear to the President that the United States must not be dragged into another war in the Middle East,” said Pingree.

Sen. Angus King, I-Maine, called the bombings both “profoundly important” and “potentially dangerous.” Like Pingree, he urged the president to consult Congress before entering a war.

“The President has taken a profoundly important — and potentially dangerous — step in ordering the bombing of Iran’s nuclear facilities and thus risking U.S. involvement in another debilitating war in the Middle East,” said King in a written statement.

“Beyond the risks entailed by the President’s decision, however, are questions surrounding the manner in which the decision was made — entirely unilaterally without consultation with our allies (except Israel), or Congress. Our Constitution explicitly places the responsibility to “declare war” on Congress for a very good reason, to avoid the danger inherent in placing that awesome power in the hands of one person,” King continued.

He said that, if possible, the president should consult Congress both as commonsense policy and “respect for the Constitution,” before effectively declaring war.

“In this way, the President would have the opportunity to present to the peoples’ representatives the intelligence basis for the decision, the pros and cons of the proposed action, and the means to be employed,” King wrote.

King said the outcomes of the strikes are yet to be determined.

“The results of these strikes may turn out to be successful — the end of Iran’s nuclear program and it’s aggression in the region — but the risks are no less real —that Iran may have nuclear facilities we don’t know about and conclude that they have no choice but to race to a bomb,” said King’s statement.

Rep. Jared Golden, D-2nd District, issued a statement Monday supporting the president’s decision.

“Iran is governed by a regime that is hostile to the United States and allied with others that seek the destruction of America,” Golden said in the statement. “They sponsor terrorist organizations that have killed American troops and citizens and are a source of chaos and bloodshed in the region. The IAEA determined the regime had been dangerously close to developing nuclear weapons. Based on what I know so far, I believe the president was right to launch limited strikes to deter that outcome.”

Golden went on to say it is important the country learns what intelligence prompted the president’s action.

“It is important now that the country learns what information helped inform the president’s decision and the timing of these strikes, and that we learn more about whether we were successful in destroying Iran’s nuclear program. I look forward to Congress receiving a full briefing.”
