Republican lawmakers Monday demanded the Biden administration release data related to the border crisis “either not being adequately monitored or being hidden from members of Congress and the public.”

The Biden administration is facing more pressure from Republicans to handle the growing migration of illegal southern border crossings as tens of thousands of individuals, many of whom are unaccompanied children abandoned at the border, continue to cross over into the United States from Mexico. The U.S. Customs and Border Protection encountered more than 172,000 people trying to gain entry along the Southwest border in March. That figure is a 71% increase over February 2021.
