Republican lawmakers grilled Alejandro Mayorkas, the embattled US secretary of homeland security, during a House judiciary committee oversight hearing on Wednesday.
Mayorkas, who has been the target of a GOP-led congressional investigation over his handling of the US-Mexico border, faced a series of tough questions regarding his tenure as head of the department, which broadly oversees US immigration and border policies. The hearing came as some House Republicans have threatened to impeach Mayorkas, the first Latino and immigrant to head the Department of Homeland Security, over his alleged mismanagement of the border.
