Taoiseach Simon Harris has commented on Trump's assassination attempt in Pennsylvania over the weekend, describing it as a "horrific, heinous criminal act."

"I'm relieved that former president Trump is secure and well, but we must always call out political violence," Mr Harris said.

He also expressed his condolences for Corey Comperatore (50), who died in the incident, and also mentioned that his thoughts were with those injured.

"My thoughts today are with the person who lost their life - the innocent spectator who went to a political event and found themselves caught up in this - and indeed those who are critically injured," Mr Harris continued. "I'm pleased that [former] president Trump is well and we send him our best."

Former US President Trump was addressing a campaign rally in Pennsylvania when he was shot in the ear. The 20-year old suspect, a registered republican, fired eight shots from a 200-yard-rifle range atop a nearby building before a Secret Service aganet shot and killed him. Reports confirm that Trump had been showing supporters a chart about illegal immigration and border crossings mere minutes into his speech before the rally turned into a crime scene.

Mr Trump survived the assassination attempt, with a bullet wound to his right ear. Speaking to the New York Post, he said "I'm supposed to be dead;" and credited the aformentioned immigration chart with saving his life, his doctor said.

The FBI said it was probing the shooting as "an assassination attempt and potential domestic terrorism."

World leaders and US elected officials from both sides of the aisle forcefully condemned the attack. President Joe Biden, in a nationally televised address from the Oval Office on Sunday evening discussed the need to "lower the temperature in our politics."

"While we may disagree, we are not enemies," he continued. "We must stand together."

Speaking to RTÉ, Sinn Fein leader Mary Lou McDonald has described the assassination attempt on the former president as "deeply, deeply shocking" and "a gamechanger."

She continued, mentioning that her first thoughts are with the man who lost his life and his family, as well as the other people who in injured in the line of fire.

"The idea of an assassination attempt on any candidate for the presidency of the United States or any political candidate, I think is shocking and it gives us all pause for concern."

Ms McDonald further commented that people who run for public office "have to be free to go about their campaigns safely."

"I would be sure that as fraught as political life is in the United States, that Democrats, Republicans, independents, everybody stands for square behind the idea that politics and democracy has to function and that means that campaigns have to be run and candidates have to have rallies and public events and to be safe."
