Did the Internal Revenue Service really lose two years worth of emails from Lois Lerner and six other IRS officials allegedly involved in the IRS – Tea Party scandal? Our tax collecting agency claims that computer crashes and discarded hard drives have resulted in the loss of many emails which Congress would love to get their hands on. Now we learn that the IRS had a contract with email backup company, Sonasoft, since 2005. But, for some strange and unknown reason, the contract was suspended in 2011 as the House Ways and Means Committee began investigating charges that the IRS had targeted Tea Party and conservative groups. While they still have internal IRS emails, those messages exchanged with the White House, Treasury Department and other outside sources are gone. IRS chief John Koskinen will be taking the hot seat again tonight during another Congressional hearing after last week′s appearance where Rep. Paul Ryan (R-WI) all but called Koskinen a liar.
