(CNN) - In a knife fight of a congressional hearing, IRS Commissioner John Koskinen defended his agency, but he sparked an uproar from Republicans by admitting it destroyed a key hard drive wanted in an investigation, and he did not apologize for the data loss.
"I don't think an apology is owed, not a single email has been lost since the start of this investigation," Koskinen told a dais full of skeptical GOP members on Friday.
He argued the IRS has done its best to find the emails that originally went missing in 2011.
