President Donald Trump said the attack in Boulder “WILL NOT BE TOLERATED” in a post on Truth Social Monday morning as the president and lawmakers in Colorado and nationwide continue to condemn the attack on demonstrators at the Pearl Street Mall on Sunday.

Speaking of the accused attacker, Trump said, “He came to in through Biden’s ridiculous Open Border Policy, which has hurt our Country so badly. He must go under “TRUMP” Policy. Acts of Terrorism will be prosecuted to the fullest extent of the Law. This is yet another example of why we must keep our Borders SECURE, and deport illegal, anti-American radicals from our Homeland.”

In acknowledging the eight victims in the post, Trump continued, “My heart goes out to the victims of this terrible tragedy, and the Great People of Boulder, Colorado!”

The attack occurred just before 1:30 p.m. Sunday near 13th and Pearl streets during a weekly event called the “peaceful humanitarian walk for hostages,” organized by the group, Run For Their Lives, which raises awareness about Israeli hostages held in Gaza.

Witnesses say a man was waiting near the historic courthouse with bottles in hand. He allegedly shouted, “free Palestine” before throwing what officials described as a makeshift flamethrower or Molotov cocktail into the crowd.

Some victims suffered burns and were transported to Denver-area hospitals. UCHealth University of Colorado Hospital in Aurora confirmed it received two patients who were airlifted from the scene.

The Boulder Police Department on Monday said none of the burn victims had died. According to 9NEWS, one victim is a Holocaust survivor.

The suspect, 45-year-old Mohamed Sabry Soliman of Colorado Springs, was booked into the Boulder County Jail on a $10 million bond.

White House Deputy Chief of Staff Stephen Miller on Sunday said on social media that Soliman had “illegally overstayed” a tourist visa.

‘Violence has no place in our state’

In a statement released Sunday evening, Gov. Jared Polis, who is Jewish and lives in Boulder, said his thoughts go out to the victims of “this heinous and targeted act on the Jewish community.”

“Boulder is strong,” he said. “We have overcome tragedies together and will get through this together as a community. I’ve spoken with Boulder Mayor (Aaron) Brockett, and my administration is working closely with local and federal law enforcement on this afternoon’s attack. I thank the first responders who ran to help the injured and ensure victims received medical attention needed and to apprehend the suspect.”

Polis said that with the Jewish community reeling from the recent antisemitic murders in Washington, D.C., it is “unfathomable” that the community is facing another antisemitic attack in Boulder.

Democratic U.S. Rep. Joe Neguse, who represents Boulder, said he was “horrified” by the attack and is praying for the victims.

“Tonight, as many prepare to mark the Shavuot holiday, our Jewish community has been subjected to yet another brutal and horrific act of violence,” he said. “The scourge of antisemitism has metastasized across our country, and we must do more — now — to stop this hatred and violence. We stand with the Jewish community — today and always — and will be united in supporting the victims and their families, and to redoubling our efforts to stop antisemitism.”

Republican U.S. Rep. Lauren Boebert, of Colorado’s Congressional District 4, blamed the attack on progressives allowing and encouraging “hate speech toward Jews for their mere existence.” She noted the recent killing of a Jewish couple in Washington, D.C. by a man who allegedly said he committed the act “for Gaza.”

“We just saw it in DC, and it’s sadly no surprise to see it in Boulder,” Boebert posted on X. “We need to forcefully condemn this rhetoric and stand with the Jewish community as they continue to be targeted by hateful lunatics. I have been in direct contact with the FBI; they need to take the lead on investigating this as an act of targeted terrorism and not left to local officials.”

Colorado State Rep. Junie Joseph, D-Boulder, called the attack a “senseless act of violence.”

“Violence has no place in our community. Targeting people based on their identity or beliefs is not only hateful and cowardly—it is fundamentally at odds with the values of peace, dignity, and inclusivity that we hold dear in Boulder and across Colorado,” she said. “I unequivocally condemn this act and all forms of hate.”

Joseph said her heart is with the victims, their families, the Jewish community, and all those who are grieving and shaken by this tragedy. In thanking first responders for their quick reaction, Joseph stressed that Boulder is home to a “thriving Jewish community that makes immeasurable contributions to the cultural, civic, and moral fabric of our city. Without their presence, leadership, and history, we would not be the community we are. Today’s attack is not just an assault on individuals—it is an assault on the very values of inclusion, freedom, and humanity that bind us together.”

Other state lawmakers, including Rep. Ron Weinberg, R-Loveland, who is Jewish and once lived in Israel, called the attack on peaceful protestors, including children, appalling.

“This country was founded on the principles of free speech, peaceful assembly, and religious freedom,” he said. “The individuals who gathered in Boulder were exercising those rights and were met with hatred. The suspect must be prosecuted to the fullest extent of the law, and law enforcement must treat this as the domestic terror incident it is.”

Colorado Attorney General Phil Weiser called the attack a likely hate crime, given the targeted nature of the group.

Boulder District Attorney Michael Dougherty stated that charges are pending and could be brought at either the state or federal level.

House Minority Leader Rose Pugliese, R-Colorado Springs, and Assistant Minority Leader Ty Winter, R-Trinidad, said they are praying for the victims and their families.

“Violence has no place in our state—especially when directed at those standing in unity for the innocent,” said Pugliese.

“Our communities have the right to feel safe while they gather in peace,” added Winter.

House Speaker Julie McCluskie, D-Dillon, and Majority Leader Monica Duran, D-Wheat Ridge, said the attack “continues a terrifying rise in antisemitism and threats against Jews, both here and abroad.”

“We stand in solidarity with Jewish Coloradans and Jews around the world who are increasingly living in fear that they will be attacked simply for being Jewish,” they said. “We agree with our Jewish colleagues that this cannot become normalized. We must commit ourselves to doing more to combat antisemitism and violence against Jews. Now is the time for Coloradans to speak up and say with one clear voice that antisemitism is unacceptable and has no place in our communities.”

Senate Democrats also released a statement condemning the attacks, with Sen. Judy Amabile, who represents Boulder, saying “divisive, hateful rhetoric” needs to stop.

“We all must commit to peace and safety in both our words and our actions,” she said. “My thoughts are with the victims, their families, and all those impacted by this tragedy. Boulder is resilient, and we will stand united against violence in all its forms.”

Sen. Dafna Michaelson Jenet, D-Commerce City, moved to the United States from Israel as a child.

“As an Israeli-born, American Jewish woman living in Colorado, I am devastated and heartbroken at the terrorist attack on my friends and colleagues at the Run for Their Lives event in Boulder,” she said. “This event is a weekly peaceful gathering of Israeli and American Jewish families working to bring attention to the hostages who are still being held in Gaza for almost two years following the massacre of the Israeli people on October 7th, 2023. All Jewish communities in Colorado and around the country are on edge as we enter into the Jewish holiday of Shavuot this evening. We live in America for the freedom it affords. Terrorism should never happen here. The violence must end.”

Colorado’s Jewish state lawmakers, including Weinberg, Michaelson Jenet, Reps. Emily Sirota, D-Denver, and Steven Woodrow, D-Denver, and Sens. Mike Weissman, D-Aurora, and Matt Ball, D-Denver, released the following joint statement on Monday:

“We are outraged and heartbroken by the vicious attack at the Run for Their Lives walk in Boulder. Innocent people were severely injured for doing nothing more than raising awareness about the 58 remaining hostages held in Gaza by Hamas. Our prayers are with the victims, their families, and the entire Boulder community.

This attack should not be viewed in isolation. In April, a man broke into Pennsylvania Governor Josh Shapiro’s residence and set it on fire while his family slept inside. In May, a Coloradan was arrested for trying to burn down the U.S. Embassy in Tel Aviv, and two people were murdered outside the Capital Jewish Museum in Washington, D.C. It didn’t matter that one of the murder victims had devoted her life to peace through interfaith dialogue, just like it didn’t matter that the victims in Boulder were marching peacefully, calling for the release of hostages and an end to war. What they all had in common was that they were Jewish. We have a name for this: antisemitism.

“Colorado’s Jewish community is strong and deeply rooted in our state’s history. As members of that community, we know that the attack in Boulder could have happened to any of us—some of us have even participated in Run for Their Lives events in the past. We will continue to live proudly and openly because Colorado must be a place where every Jew feels safe, supported, and free. But we cannot fight antisemitism alone—to stand up to hate, we need Coloradans to stand with us.

As we mourn the victims of yesterday’s attack in Boulder, we ask our allies to speak out. Whether publicly or privately—and regardless of views on the conflict in the Middle East—we must confront hate forcefully, before it becomes normalized. The rising tide of antisemitic attacks doesn’t just threaten Jews. It threatens the very fabric of what makes America worth believing in. We should all be outraged to live in a country where this is happening—and determined to change it.”
