Two senior border patrol officials will headline this week's House hearing on the Biden administration's open border policies.
DHS Secretary Alejandro Mayorkas previously blocked their testimony, but the agency eventually caved to threats of subpoena.
"The reason for that is because these same top officials have had to testify in some of the court cases, the litigation against the Biden policies. Under oath, their remarks have been devastating to the picture the Biden administration wants people to have," says Jessica Vaughan, director of policy studies at the Center for Immigration Studies.
Their testimony comes a week after House members heard from a sheriff, distraught father and El Paso County's Democratic judge who dismissed both.
"A father whose son was killed by fentanyl poisoning, only to have these concerns dismissed as lies and racism," says Vaughan.
"It's really hard to see how we can get past this partisanship and take practical steps to secure the border and address this mass illegal migration."
Senior agents from the Rio Grande Valley and Tucson sectors will testify Tuesday.
