Unsurprisingly. It’s not as though Republicans were going to pass by a chance to make a Biden appointee look bad.
I thought Austin comported himself well. For me the big takeaway was the (former, at least) difference between rules for Cabinet secretaries and rules for Presidents as laid out in the Constitution. Rules for Cabinet people aren’t going to become part of the Constitution, but if the consensus is that the rules for both should be similar (or analogous), then that will happen.
Austin’s best lines were about the fact that Congress hasn’t been making one-year budgets for a while, now–and that the security of the nation would be enhanced if they’d actually put in the work of doing a full-year appropriation.
