The U.S. Border Patrol captured nearly 9,000 migrants in one day

The Biden administration is increasing migration control efforts as Southwest unlawful border crossings rise.

The U.S. Border Patrol captured about 9,000 migrants on Wednesday, according to officials who declined to talk about preliminary data. Rural southern Arizona, especially Tucson, and south Texas have seen major migration increases.

Border Patrol officials at Eagle Pass, Texas, "swiftly vetted and processed" 2,500 migrants arrested at the border on Wednesday, according to CBP. Rail and automobile traffic was stopped at various border crossings for enforcement.

According to a CPB statement, only section of the international railway bridge in Eagle Pass was reopened for vehicle processing early Saturday.

The newest Customs and Border Protection data shows 181,059 southern border apprehensions in August, up from 132,648 in July. Over 232,000 migrants were arrested or jailed in the Southwest, peaking since December.

Compared to 245,213 in July, authorities encountered migrants more than 300,000 times last month.

New statistic indicates Biden's largest monthly total ever.

While the Biden administration is taking steps to reduce the southern border surge, immigration are increasing. Immigration advocates argue the president is not doing enough to alter immigration rules, while Republicans claim the administration is not doing enough to safeguard the borders.
