House Republicans investigate DHS Secretary Mayorkas for dereliction of duty at southern border.

House Republicans are launching an investigation into Homeland Security Secretary Alejandro Mayorkas for alleged "dereliction of duty" regarding his handling of the border. The investigation comes amid calls from some Republicans to impeach Mayorkas. The hearing will include testimony from former acting DHS Secretary Chad Wolf and former Border Patrol Chief Rodney Scott. Illegal immigration has skyrocketed at the U.S.-Mexico border under Mayorkas and President Biden's leadership.
