So far, Republicans on the House coronavirus crisis subcommittee have focused their questioning on crowded conditions in facilities along the US-Mexican border.
House minority whip Steve Scalise shared photos of his trip to the southern border, which showed some of those crowded facilities.
Scalise quoted the guidance from the Centers for Disease Control and Prevention warning against travel to Mexico due to concerns about coronavirus spread.
Scalise asked Dr Rochelle Walensky, the CDC director, whether her agency’s guidance applied to all people flying from Mexico, not just Americans, and she confirmed that it applied to all air travelers.
