Members of Maine’s congressional delegation condemned political violence following a shooting at former President Donald Trump’s rally in Butler, Pennsylvania, on Saturday that is being investigated as an assassination attempt.

Trump said Saturday night that he had been shot in the ear. One spectator was killed, and two were critically injured.

“Thanks to the quick action of the Secret Service, I am glad to hear former President Trump is safe and wish him a speedy recovery,” Sen. Angus King, I-Maine, wrote Saturday night on the social media platform X. “We can disagree on politics, but political violence of any kind is wrong and antithetical to the core American values we believe in.”

When shots rang out, Secret Service agents whisked Trump off the rally stage. The presumptive Republican nominee was seen with blood on his face.

The FBI identified the shooter Sunday morning as Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania. The Secret Service fatally shot Crooks.

Trump was pierced in his upper right ear but is doing “fine,” his campaign said.

Sen. Susan Collins, R-Maine, praised the Secret Service’s response Saturday night on X.

“I am very relieved that President Trump appears to be OK; however, this violence is absolutely appalling,” Collins wrote. “Thank God for the Secret Service and first responders who hurried President Trump out of harm’s way.”

President Biden addressed the nation in Delaware two hours after the shooting, saying “everybody must condemn” the apparent assassination attempt. In an Oval Office address Sunday, Biden reiterated those calls and declared that “we must never descend into violence.”

Maine’s Democratic representatives joined Biden in denouncing the attack and expressing support for the attendees of Saturday’s rally.

“The assassination attempt last night on former president Trump is horrifying and we should all be relieved he was not seriously injured. My heart goes out to the victims and their loved ones,” Rep. Chellie Pingree, D-1st District, said in a statement on Sunday afternoon. “Political violence of any kind has no place in America. Our disagreements and differences should be expressed with votes at the ballot box, not bullets.”

Rep. Jared Golden, D-2nd District, wrote in an X post that he is “praying for former President Trump and others at the rally today in PA, as well as for law enforcement on the scene.”

In a lengthier statement Sunday afternoon, Golden echoed his previous calls for unity amid a divided election.

“This is the moment for elected officials and candidates for political office to lead us down a better road toward the hopeful future that Americans want and deserve,” Golden said.

“As I have said before, this election should not be misleadingly portrayed as a no-holds-barred struggle between democracy or authoritarianism, or a battle against fascists or socialists intent on destroying America as we know it. These are dangerous lies,” the statement read.

“We need to look to the future with clear eyes: Our country faces many challenges at home, and abroad the world is increasingly unstable and dangerous. Yet we remain a strong, democratic and wealthy nation capable of overcoming these hard times if we are united in pursuit of our common interests. Divided, we are likely to fail.”
