A bipartisan group of lawmakers in Congress representing border states introduced legislation on Thursday aimed at responding to “the surge” at the U.S.-Mexico border by creating “regional processing centers” along the southern border to process migrants.

Republican Sen. John Cornyn and Rep. Tony Gonzales of Texas, along with Texas Democratic Rep. Henry Cuellar and Democratic Sen. Kyrsten Sinema of Arizona, joined together to present the Bipartisan Border Solutions Act, which attempts to help the federal government better manage influxes in migration.
