A wave of business leaders offered supportive words and condemnations of political violence in the hours and days after Donald Trump survived an assassination attempt.

President Joe Biden also condemned the attack, calling on Americans to "cool it down" in a rare address from the Oval Office.

A shooter opened fire during a campaign rally near Butler, Pa., on Saturday evening, and Trump was injured when his ear was pierced before he was rushed away by the Secret Service. One member of the audience was killed.

"I pray for President Trump's rapid recovery," wrote Apple (AAPL) CEO Tim Cook, adding: "I strongly condemn this violence."

It was a sentiment shared by many.

"We’re heartbroken for the victims and their families," added Walmart (WMT) CEO Doug McMillon in his own comment.

"Just awful," said Amazon (AMZN) CEO Andy Jassy.

Jassy's predecessor, Jeff Bezos, added that "our former president showed tremendous grace and courage under literal fire tonight."

The supportive sentiments were seen across the political and business worlds and shared by many top C-suite leaders, including some who have clashed with Trump over the years.

"Praying for a quick recovery for President Trump," wrote Meta (META) CEO Mark Zuckerberg. "Political violence undermines democracy and must always be condemned."

Other similar statements were seen from figures from the CEO of Microsoft (MSFT) to Airbnb (ABNB) to Alphabet (GOOG) to BlackRock (BLK) and others.

"A very difficult night for our nation," added Intel (INTC) CEO Pat Gelsinger.

Trump was taken to a hospital after the attack and assessed before being released. He posted a thanks to first responders online.

The former president followed up on Sunday morning by saying he is looking forward to speaking later this week at the Republican National Convention. He then traveled to Milwaukee where the proceedings are set to begin on Monday evening.

The Secret Service says that the suspected shooter was killed after making an attack "from an elevated position outside of the rally venue." Two other rally attendees were critically injured.

President Joe Biden and other political leaders in both parties offered their support, as did world leaders. The president said in his televised remarks that "there is no place in America for this kind of violence. It's sick. It's sick."

He then spoke to Trump on the phone later in the evening and followed up with more appearances Sunday from the White House, including an address to the nation where he announced a national security review of the incident.

The Business Roundtable, a group of leading CEOs, called "on all Americans to reject political violence and to commit to resolving political differences peacefully."

The Chamber of Commerce, National Association of Manufacturers, and other business groups also released statements condemning political violence.

Some new political support for Trump

The aftermath also some new political support for the former president in his campaign against President Biden.

Tesla (TSLA) CEO Elon Musk said, "I fully endorse President Trump and hope for his rapid recovery" just 30 minutes after the shooting.

He also seemed to endorse J.D. Vance later in the night as Trump's vice presidential pick and offered a string of commentary, including condemnations of the Secret Service.

Musk's formal support isn't necessarily a surprise. He has long been complimentary of Trump and critical of Biden. He even, according to a recent Wall Street Journal report, talks with Trump on various issues multiple times a month.

The endorsement also came after Bloomberg reported Friday night before the shooting that Musk had made his first donation of the 2024 election with a donation to a Trump-aligned super-PAC called America PAC.

Trump received another formal business world backer in the aftermath of the violence when Pershing Square CEO Bill Ackman posted a formal endorsement.

Like Musk, Ackman has long been critical of Biden and supportive of Trump, and he noted in his post that "I came to this decision some time ago" and that it likely wouldn't be a surprise to his followers.
