“There was a shooting this morning at the Dallas ICE Detention Facility,” Noem wrote on X. “Details are still emerging but we can confirm there were multiple injuries and fatalities. The shooter is deceased by a self-inflicted gunshot wound.”

“While we don’t know motive yet, we know that our ICE law enforcement is facing unprecedented violence against them. It must stop. Please pray for the victims and their families,” she added.

Authorities said the gunman opened fire as the sally port was opened for a detainee transfer, attempting to force entry into the facility. It remains unclear whether he is among the three people reported shot, Fox News.

“The obsessive attack on law enforcement, particularly ICE, must stop. I’m praying for everyone hurt in this attack and for their families,” Vice President JD Vance wrote on X.

Sen. Ted Cruz, R-Texas, confirmed Wednesday morning that he is aware of the shooting and said his team is monitoring the situation.

“My team and I are closely monitoring the situation at the ICE Detention Facility in Dallas. We are praying for the swift recovery of those injured, and we are deeply grateful to the brave first responders who rushed to the scene,” Cruz wrote.

California Governor Gavin Newsom sparked controversy on Saturday after his team posted a cryptic message directed at Noem.

Newsom has positioned himself as a leading opponent of the Trump administration, especially on immigration, CNN reported.

That feud intensified earlier this year when President Donald Trump dispatched ICE agents to Los Angeles for large-scale deportation operations.

Against that backdrop, Newsom’s press team posted a statement that many interpreted as a threat toward Noem.

The post read, “Kristi Noem is going to have a bad day today. You’re welcome, America.”

Several X users quickly compared the message to ominous comments made online before the assassination of conservative activist Charlie Kirk.

Also, the Trump administration blasted Team Newsom’s message to Noem.

Tricia McLaughlin, assistant secretary at the Department of Homeland Security, accused the governor of hiding behind his staff.

“This reads like a threat,” McLaughlin wrote. “This is ugly, @GavinNewsom.”

“Your keyboard warrior team may hide behind their laptops and spew this kind of vitriol but you would never have the guts to say this to her face,” she added.

Acting U.S. Attorney Bill Essayli announced the alleged threat has been referred to the Secret Service.

A Secret Service spokesperson confirmed receipt of the referral.

“To preserve operational integrity, we are not able to comment on specific protective intelligence matters,” the statement said. “However, the Secret Service must vigorously investigate any situation or individual, regardless of position or status, that could pose or be perceived as posing a threat to any of our protectees. Especially in a politically charged climate, such as this.”

Hours later, Newsom’s press office issued a clarification, saying the original message was referencing immigration-related legislation the governor had signed into law.

That legislation includes a provision banning federal law enforcement from wearing masks in the state.
