WASHINGTON (NEXSTAR) – Leaders in Washington are condemning the terror attack in Boulder, Colorado that left eight injured this weekend.

A suspect is in custody after investigators say he attacked eight people Sunday in Boulder with a makeshift flamethrower and shouted, “Free Palestine.”

The injured were demonstrating for Hamas to release Israeli hostages.

Colorado Senator Michael Bennet condemned the attack.

“The people in Boulder, Colorado were savagely attacked by a terrorist while they were expressing their First Amendment rights. that should never happen in this country,” said Bennet.

The FBI is investigating this as an act of terrorism.

Senate Democratic Leader Chuck Schumer is urging authorities to fully investigate.

“After all, all they were doing was expressing a simple plea: bring the hostages home. And because of their Jewish identity, they were targeted by hate,” said Schumer.

According to the Department of Homeland Security, the suspect, 45-year-old Mohamed Soliman was in the country illegally.

The White House says President Trump stands with Jewish Americans and with its plans to deport illegal immigrants.

“This terrorist was allowed into this country by the previous administration who was foolishly given a tourism visa and then was illegally allowed to stay. These individuals are going to be deported, and we’re not going to tolerate such violence in our country,” said White House Press Secretary Karoline Leavitt.

President Trump posted on Truth Social, “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,”

The attack comes just over a week after a man was charged with fatally shooting two Israeli embassy employees in Washington, D.C.

He also shouted, “Free Palestine.”
