The head of U.S. Border Patrol is leaving the agency, which is tasked with securing the U.S. border, in the latest shakeup of immigration enforcement leadership in the Trump administration.

U.S. Customs and Border Protection Commissioner Rodney Scott said in a statement to NBC News that the agency thanked U.S. Border Patrol Chief Michael Banks “for his decades of service to this country and congratulate him on his second retirement after returning to serve during one of the most challenging periods for border security.”

“During his time as Chief, the border was transformed from chaos to the most secure border ever recorded,” Scott said. “We wish him and his family well.”

He served as Border Patrol chief for the entirety of Trump’s second term.

Banks first announced he was resigning effective immediately in an interview with Fox News.

“It’s just time,” Banks told Fox News. “I feel like I got the ship back on course from the least secure, disastrous, chaotic border to the most secure border this country has ever seen.”

“Time to pass the reigns, 37 years, it’s time to enjoy the family and life,” he said.

Bank’s departure is the latest leadership shake-up of officials implementing President Donald Trump’s immigration crackdown and comes as the Republican administration appears to be recalibrating its approach.

The White House did not immediately respond to a request for comment.

It was not immediately clear who will replace Banks. He led an agency at the forefront of Trump’s high-profile immigration enforcement efforts but kept a lower profile than some other officials such as Gregory Bovino, a now-retired commander who became a public face of the city operations.

CBP is one of the federal agencies that participated since last year in a series of immigration enforcement operations, carried out primarily in cities governed by Democrats —an effort that triggered a spike in arrests and led to the fatal shooting of two U.S. citizens in Minneapolis this year at the hands of federal immigration officers.

Banks’ resignation takes place two months after Markwayne Mullin, a former Republican senator from Oklahoma, became homeland security secretary. DHS oversees CBP and U.S. Immigration and Customs Enforcement, also known as ICE.

Banks is stepping down at the same time that ICE is also going through a leadership transition. Todd Lyons, the acting ICE director, is leaving later this month and will be replaced by David Venturella, who worked for years for private contractors before returning to government service.

CBP was established in 2003 and handles customs, immigration, and agricultural regulations to secure U.S. borders.

Banks returned to the Border Patrol last year after a long agency career that had never landed him in its senior ranks. His star had risen as border czar to Gov. Greg Abbott, R-Texas, during a period when illegal crossings reached record highs and the state launched a multibillion-dollar enforcement surge that led to turf battles with the Biden administration.

Banks kept a relatively low public profile as arrests for illegal crossings have plunged to their lowest levels since the mid-1960s, a trend that began toward the end of that Democratic administration.

Banks did not appear publicly at the Border Security Expo this month in Phoenix, an annual conference at which government officials update contractors on the state of the border. Scott, who was Banks’ supervisor, is a close ally of Trump border czar Tom Homan and has acted more as the agency’s public face.
