The Biden-Harris administration is reportedly admitting that it falsely claimed it vetted an Afghan terrorist suspected of planning an attack for ISIS before allowing him to enter the United States.

Federal authorities arrested 27-year-old Nasir Ahmad Tawhedi in Oklahoma last week on multiple terrorism charges for allegedly plotting an Election Day terrorist attack the FBI now says was being directed by ISIS-K, the terror group’s Afghan branch.

Investigators initially claimed Tawhedi was brought to the United States after being vetted under the Special Immigrant Visa program. The Biden-Harris administration maintained that claim, even after sources told NBC News last week that Tawhedi was not vetted, and was instead admitted to the United States through the more lax humanitarian parole system.

But the Biden-Harris administration now admits that Tawhedi “was never vetted or approved” by the State Department for Special Immigrant Visa status, according to Fox News. Sources said that Tawhedi, who worked as a security guard for the CIA in Afghanistan, was “not well known” by the U.S. government when the Biden-Harris administration brought him to the country.

The administration has faced severe backlash over its open border policies, which have led to a historic number of terrorist suspects entering the country amid an influx of 10 million illegal aliens.

Homeland Security Secretary Alejandro Mayorkas, the first cabinet secretary in history to be impeached, was hostile last week to a reporter who asked him about his department’s failings related to Tawhedi. Tawhedi illegally obtained weapons and ammunition for the attack which he told law enforcement officials was “targeting large gatherings of people.”
