“You can smile and laugh about it all you want,” Rep. Jason Chaffetz (R., Utah) bristled at Mr. Geithner during a House Budget Committee hearing. Mr. Chaffetz then intoned he was getting sick of the Treasury secretary’s “silly little smirk.” To be sure, Mr. Geithner did have a smile on his face during parts of the hearing, particularly when he was interrupted by Republicans on the panel when they didn’t like his answers on deficit reduction. He even spent part of the hearing answering questions with his arms crossed. At one point, he suggested that Rep. Tim Huelskamp (R., Kan.) had an “adolescent perspective” on how the economy worked.
