Texas Congressman Kevin Brady (R-The Woodlands) was right in the middle of a heated hearing before the House Ways and Means Committee on Friday. IRS Commissioner John Koskinen was grilled over how the agency lost years' worth of e-mails belonging to Lois Lerner, the woman at the center of the agency's targeting of conservative political groups.  The IRS notified Congress last week that they are missing nearly two years' worth of Lerner's e-mails because of a computer crash in 2011.  Brady accused Koskinen of intentionally misleading the committee last month when he promised to deliver "all" of Lerner's e-mails without limitation.  Brady also pointed to a letter showing that the Treasury Department was already aware of the missing e-mails before Koskinen's promise to the committee.

After Koskinen insisted he had not misled the committee and that he wasn't aware of the missing e-mails at the time of his prior testimony, Brady went off.  "At this point, why should anyone believe you," he asked Koskinen.  "The IRS denied for two years targeting Americans based on their political beliefs--that wasn't the truth.  They said it was a few rogue agents in Cincinnati--that wasn't the truth.  You said you were targeting liberal organizations--that wasn't the truth.  And now, you're telling us out of thousands of IRS computers, the one that lost the e-mails was of the person of interest in an ongoing Congressional investigation.  This is the most corrupt and deceitful IRS in history."

Brady continued his tongue-lashing of the IRS and Koskinen in a statement released after the hearing, in which he said, "It's apparent (Koskinen) is no longer working for the American people, but is one more in a long line of recent acting IRS commissioners whose main purpose is to mislead investigators and cover up this scandal."
