President Donald Trump on Monday demanded the deportation of Boulder, Colorado terrorist attack suspect Mohamed Soliman in his first public comments on Sunday’s incident that injured eight people.

“Yesterday’s horrific attack in Boulder, Colorado, WILL NOT BE TOLERATED in the United States of America. He came in through Biden’s ridiculous Open Border Policy, which has hurt our Country so badly,” Trump posted to his Truth Social account, referring to Soliman.

“He must go out 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. My heart goes out to the victims of this terrible tragedy, and the Great People of Boulder, Colorado!” the president’s statement concluded.

Homeland Security Assistant Secretary Tricia McLaughlin tweeted Monday that Soliman “is illegally in our country.”

McLaughlin said Soliman “entered the United States in August 2022 on a B2 visa,” which is issued to tourists.

The visa expired on February 2023, she said.

“He filed for asylum in September 2022,” according to McLaughlin.

Soliman, 45, told police he planned the attack for a year and specifically targeted what he described as the “Zionist group,” the FBI said, according to the Associated Press.

Soliman allegedly used a makeshift flamethrower and an incendiary device to carry out the attack during a Jewish community event supporting Israeli hostages in Gaza.

Eight people were injuredin the attack, some with burns, as a group was concluding their weekly demonstration to raise visibility for the hostages who remain in Gaza. Witnesses reported the man yelled “Free Palestine” during the attack.

An FBI affidavit says Soliman confessed to the attack after being taken into custody Sunday and told the police he would do it again.

Court records show Soliman was scheduled to appear in state court in Boulder at 1:30 p.m.

On Monday morning, Boulder police said it would be holding a press conference “later today” on the attack.
