As Stephen Dinan reports, Homeland Security Secretary Alejandro Mayorkas graded himself with an “A for effort” this week, telling senators he believes the Biden administration is on the right track to solve the border’s chaos and to make up for what he called cruel Trump policies. His defense was not reassuring to Republicans on the committee. Plus, sheriffs representing 17 states called on President Biden to oust Mayorkas and find a new department chief who will work with them to restore respect for the border and immigration law.
