There are plenty of reasons to criticize Issa, but the big move that Issa pulled today in committee deserves credit.
He unloaded subpoenaed IRS emails into the public domain for the court of public opinion to digest by holding a hearing on this matter today.
Go read the Lois Lerner emails and forget the show that was on TV so Issa could make this data dump according to committee rules. So read up and educate your friends.
Oh, yeah? Why didn't he keep her there all day long taking the Fifth while unloading even more subpoenaed emails? Wouldn't that have been better for the court of public opinion?
Issa is a loser (see Issa's Fast and Furious investigation).
