A group of 11 Democratic and Republican senators has introduced legislation to block the Biden administration’s attempt to end the pandemic border policy that allows officials to turn away illegal migrants at the border.

Five Democrats and six Republicans, including several facing tough reelection bids in November, introduced the Public Health and Border Security Act of 2022 on Thursday, which would override the White House’s plan to end the pandemic policy known as Title 42 on May 23. Lawmakers in both parties have warned that ending Title 42 and ending the practice of immediately sending migrants back to Mexico will lead to a rush at the border.
