The Biden-Harris administration is facing criticism over border policies after eight ISIS terror suspects from Tajikistan, who illegally crossed the border, were arrested over the summer for planning a terrorist attack in the U.S.

Federal law enforcement officials arrested the suspects in coordinated raids in Los Angeles, New York, and Philadelphia after learning that they were actively plotting to carry out an attack on U.S. soil.

CBS News reported that after four months, three of the suspects have been deported to Tajikistan and Russia while four additional suspects are in custody and expected to be removed in the coming weeks.

The eighth suspect will likely face a similar outcome but is waiting for his judicial proceedings after they were delayed for a medical issue, the report said.

“It’s good that three potential national security threats have been removed from the country,” House Homeland Security Chairman Mark Green (R-NC) told The Daily Wire. “However, they shouldn’t have been here to begin with. Some even reportedly used Biden and Harris’ CBP One mass-parole scheme to enter!”

Green said that he was deeply concerned about the number of “possible terrorists, gang members, and individuals with criminal backgrounds” that have been released into the country by the Biden-Harris administration after illegally crossing the border.

He also said he was concerned about how many of those individuals entered the country illegally among the two million “gotaways” who evaded law enforcement and are now roaming the streets of America.

However, the decision to deport the illegal alien terrorist suspects instead of prosecuting them could be shortsighted and prove to be a national security threat later down the road.

“If we are only deporting and not prosecuting foreign nationals with terrorist ties, how soon will we see these same previously deported criminals return and enter undetected to carry out a terrorist attack?” a former senior federal law enforcement official told The Daily Wire.

“These individuals are dedicated to their cause, they do not fear jail or death,” the former official added. “There is no shortage of Mexican human smuggling groups willing to use specially vetted routes to cross high-value clients willing to pay top dollar.”

FBI Director Christopher Wray warned late last year that terrorists were trying to exploit the open southern border policies of the Biden-Harris administration.

“I am concerned that we are in an elevated threat environment, a heightened threat environment from foreign terrorist organizations for a whole host of reasons,” Wray said. “And obviously their ability to exploit any port of entry including our southwest border is a source of concern. There’s a lot of discussion about numbers and numbers are important, but let’s not forget that it didn’t take a big number of people on 9/11 to kill 3000 people. So while numbers are important, numbers don’t tell the whole story. And we have seen an increase in so-called KSTs, Known or Suspected Terrorists attempting to cross over the last five years.”
