Trump administration officials are sounding the alarm over “the biggest national security vulnerability this country’s ever seen,” warning Americans to “prepare now” for a possible large-scale attack like 9/11.

On Monday, border czar Tom Homan expressed deep concern during an appearance on Fox News, stating he is “convinced” that the United States is on the brink of a major terrorist event that “scares the hell outta [him]” —one he attributes directly to President Biden’s immigration and border policies.

“It’s coming,” Homan said, referring to the likelihood of an attack carried out by individuals who entered the country illegally through the southern border. He pointed specifically to the estimated two million “gotaways”—migrants who evaded capture by Border Patrol—as a critical national security threat, surpassing even the ongoing crises of drug and human trafficking.

“These 2 million known gotaways scares the hell out of me,” Homan said, adding that he fears some could be terrorists.

“I’m convinced something’s coming unless we can find them,” he warned. 

NY Post reports: Homan noted that it was alarming to him that millions of migrants went to great and expensive lengths to avoid detection when the Biden administration was quickly releasing illegal border-crossers into the US. 

“Why did 2 million illegal aliens pay more to get away?” Homan told Hannity. “They could have paid half of what they paid to cross the border, turn themselves in to Border Patrol agents, get released that same day, get a free airline ticket to the city of their choice, get a free hotel room, get three meals a day, plus free medical care and work authorization.”

“Two million people paid more to get away,” he argued. “They didn’t want to be vetted. They didn’t want to be fingerprinted. Why?”

“This scares the hell out of me and I’ve been doing this for 40 years. It should have scared the hell out of every American what the Biden administration did.” 

Homan described the “gotaways” as “the biggest national security vulnerability this country’s ever seen” and predicted the US will be grappling with the effects of Biden’s border policies “for the next 10 years.”

The border czar’s comments come one day after a madman who was in the country illegally torched and injured 12 people with a makeshift flamethrower and Molotov cocktails in an antisemitic terror attack in Boulder, Colorado. 

The suspected firebomber, Mohamed Sabry Soliman, is a 45-year-old Egyptian national who entered the country on a tourist visa in 2022, sought asylum and later obtained a work permit from the Biden administration, according to the Trump administration.
