Here (free content). Makes for interesting reading. An excerpt:
Time and again, lawmakers effectively stepped on their own lines, asking Cordray important questions and never bothering to let him respond. They allowed theatrics to trump (pun intended) substance, using their time to berate the CFPB chief instead of engaging in a productive discussion.
Generally, the exchanges worked like this:
The lawmakers asks a question.
Cordray starts to answer.
The lawmaker interrupts Cordray, yelling at him that he hasn't answered the question.
Blackwell provides examples of these exchanges in the column.
