Eighteen Republican attorneys general have joined a lawsuit seeking to force Joe Biden’s White House to keep the Trump-era Title 42 in place.

With just over five weeks until the Biden administration plans to roll back Title 42, the Republican attorneys general are locking arms in a display of unified opposition to the administration’s policies at the country’s southern border.

The suit to stop the administration from revoking Title 42 was originally filed by the attorneys general of Arizona, Louisiana, and Missouri. On Friday, the New York Post reported that attorneys general from 18 other states joined the suit. They are Alabama, Alaska, Arkansas, Florida, Georgia, Idaho, Kansas, Kentucky, Mississippi, Montana, Nebraska, Ohio, Oklahoma, South Carolina, Tennessee, Utah, West Virginia, and Wyoming.

Alaska’s Republican Governor Mike Dunleavy enthusiastically backed the multi-state suit. He said, “The Termination Order is detrimental to the states tasked with enforcing immigration standards, and it is not logically appropriate.”
