US homeland security chief to face hostile Republicans over border policies

Alejandro Mayorkas expected to face tough series of questions at hearing, which could be precursor to an impeachment process

Republican lawmakers are set to throw fire at Alejandro Mayorkas, the embattled US secretary of Homeland Security, during a House judiciary committee oversight hearing Wednesday.

Mayorkas, who has been the target of a GOP-led congressional investigation over his handling of the US-Mexico border, is expected to face a series of tough questions regarding his tenure as head of the department, which broadly oversees US immigration and border policies. The hearing could also be a precursor to an impeachment process that some House Republicans have threatened over the past few months.
