The partial government shutdown of the Department of Homeland Security could impact how the federal government is able to address potential terror threats in the U.S., a public safety expert said, warning that the escalating conflict with Iran could encourage those wishing to harm Americans.
Jeffrey Halstead, a retired police chief in Fort Worth, Texas, and a former commander for Homeland Security for Phoenix police, told Digital that U.S. military actions could “escalate the mindset of some of these outlying or outlier terrorist entities” wanting to take action.
“We’ve seen historically that any time there is a conflict, especially in the Middle East with escalating tensions, military action and now a declaration of war, there is a significant impact on the ability for us to work collectively to share intelligence and gather information in a timely manner from our federal partners,” Halstead said. “With the current Department of Homeland Security shutdown, if something were to occur here in the United States, there could be some significant delays because FEMA and other very, very critical divisions of the federal government are basically shut down.”
He specifically pointed out the terrorist attack in Austin, Texas, over the weekend, which left 2 people dead and 14 injured. The suspect, Ndiaga Diagne, a 53-year-old naturalized citizen born in Senegal, was also killed.

Authorities said they are investigating the shooting, which took place at a bar at about 2 a.m. on Sunday, as a “potential nexus to terrorism” as Diagne appeared to wear a “Property of Allah” sweatshirt and an undershirt depicting the Iranian flag. A Quran was also later recovered from his vehicle, and an Iranian flag and images of regime leaders were found at his home.
That attack comes after U.S.-Israeli joint military strikes, which began against Iran on Saturday morning, killed the Islamic Republic’s Supreme Leader Ali Khamenei and other leaders, triggering a wider conflict in the Middle East.
Halstead, who is also the director of strategic accounts at Genasys, a communications hardware and software provider that helps communities during emergencies, warned that events in the U.S. later this year, such as World Cup soccer matches and America’s 250th anniversary, could make the U.S. an “escalated target” if the conflict in the Middle East remains active.

He also said anytime there is a government shutdown, there seems to be a “pretty significant distraction, both politically and administratively, in every facet of our federal government and the manner in which the government operates.”
“Sometimes there is reduced staffing in some of these critical agencies, and some of the agencies aren’t being funded at all,” he said. “This will delay and possibly impede some of that critical intelligence, which could be terroristic threat level intelligence, that needs to be in the hands of local police, so that the beat officers, the patrol officers, as well as all the supervisors, understand the latest and greatest threats, including high-profile targets that could be on the radar of some of these active cells in the United States.”
He added that the government shutdown has an impact on the ability to “get that intelligence as fast as possible into the hands of those that need it” and that delays could be “very, very catastrophic” if the information is ignored or not sent.
Halstead noted that he has not seen any evidence that the shooting in Austin is directly tied to the government shutdown.

“However, when there are military actions overseas, especially in a lot of these high-profile terrorist organizations or terrorist hosting countries, it elevates the mindset for other people to take actions against American citizens and institutions in America,” he explained. “That could be schools and religious sites, and it could be the way that we live our lives with freedom.”
“When these incidents overseas happen that are terror-related, it does instill in the mindset of some of these lone wolf-style actors to take action,” he continued. “And if you look at [the case in Austin], that is exactly what the FBI has profiled to date, that this was a lone wolf probably acting upon the military action that was taken against Iran, and then wearing a shirt, ‘Property of Allah,’ that speaks to his either religious belief and/or possibility of some terroristic ties.”
DHS SHUTDOWN LOOMS OVER MAR-A-LAGO SHOOTING AS UNPAID SECRET SERVICE AGENTS NEUTRALIZE ARMED SUSPECT
In a statement to Digital, Department of Homeland Security Secretary Kristi Noem said: “I am in direct coordination with our federal intelligence and law enforcement partners as we continue to closely monitor and thwart any potential threats to the homeland.”
DHS, President Donald Trump and Republican lawmakers on Capitol Hill continue to place blame on Democrats for the shutdown. After the conflict with Iran began over the weekend, Democratic lawmakers remain unmoved, including those who voted to end the government shutdown in November.
Sen. Tim Kaine, D-Va., argued that DHS still has plenty of money left from Trump’s spending bill signed last year and that Democrats are not going to suddenly abandon their demands for reform. Sen. Angus King, I-Maine, told The Hill that he sees no correlation between the funding negotiations and the ongoing war in Iran.
“I don’t think there’s any relationship between FEMA and Iran — or the Coast Guard, for that matter,” King said.

Republicans contend that the conflict makes DHS funding even more necessary, with House Majority Leader Steve Scalise, R-La., writing on X: “Following the successful strikes on Iran and the FBI’s warning of elevated threats here at home, it is dangerous for Democrats in Washington to keep the Department of Homeland Security shut down.”

Halstead said the funding fight “looks like all the other shutdowns that we’ve seen,” adding that it “becomes one side against the other, and then they will make some strong allegations and statements and then publicly the other side will make retaliation.”
“This is probably some of the worst infighting I think I’ve seen in almost 40 years,” he said.
