Jack Teixeira, 21, a Massachusetts Air National Guard member, was taken into custody from his home under investigation for the transmission of "classified national defense information."

The arrest

"Teixeira will have an initial appearance at the U.S. District Court for the District of Massachusetts, Garland said," according to the Daily Wire.

"Roughly half a dozen FBI agents 'pushed into a residence' and arrested Teixeira. Photos and videos posted on social media showed a large law enforcement presence outside the home as helicopters swarmed overhead," it added.

Security review underway

"Defense Secretary Lloyd Austin has just said he is launching a review of 'intelligence access, accountability and control procedures' within the Pentagon in the wake of the leaked documents," according to the BBC.

"In a short statement sent out on Thursday evening, Austin thanked authorities for their 'swift arrest' of the suspect earlier today and said DoD and its national security partners would 'continue to review the national security implications of this unauthorized disclosure,'" the report added.

This is a completely valid question many Americans are asking, "How was a 21-year-old reservist Jack Teixeira (being arrested here) able to gain access to highly classified US intel?" Any idea? pic.twitter.com/l5cUleqVPa

Many Americans are questioning how a 21-year-old National Guard member had access to highly classified intelligence information.

While most Americans were thankful for the arrest, some have sided with Teixeira, labeling him as a hero or whistleblower for sharing the classified documents.

"Military records show that Teixeira holds the rank of airman first class and has been in uniform since he entered the Air National Guard in September 2019. He has been based at Otis Air National Guard Base on Cape Cod and is assigned as a cyber transport systems journeyman," according to NBC News.

"A Facebook post in July from the 102nd Intelligence Wing, which is headquartered at that base, congratulated a person with Teixeira’s name on a promotion to airman first class," it also noted.

The latest updates offer many still-unanswered concerns but at least provide a swift arrest of the alleged leaker involved in the case.
