US Border Patrol chief Michael Banks resigns

The chief of US Customs and Border Patrol (CBP) has announced that he is resigning, telling Fox News that his departure is effective immediately.

Michael Banks had been in the role since US President Donald Trump's return to the White House last year.

His departure is the latest shakeup for the Trump administration's immigration policy team, after the president fired his secretary of Homeland Security Kristi Noem earlier this year, and outspoken CBP commander Greg Bovino quit before that.

"It's just time," Banks told Fox News on Thursday. "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," he said.
