Sen. Mary Landrieu (D-LA) has been silent on the Internal Revenue Service (IRS) scandal ever since the news broke years ago that the agency was mistreating conservative groups under former IRS Director Lois Lerner. So it comes as no surprise that when Lerner and the IRS claim “the dog ate her e-mails for two years,“Landrieu still does not speak up, or give the money back that she gladly took from an IRS-related union.

Landrieu has benefited from Washington Democrats’ close relationship with the IRS, accepting $25,500 from the National Treasury Employees Union, which covers IRS employees.

But not only is Landrieu not giving the money back, she is also not demanding that the IRS handover Lerners’ e-mails between January 2009-April 2011, the period that the IRS claims it had a “computer crash” and wiped everything out. Rather, Landrieu has been mum on the issue.

A National Republican Senatorial Committee spokesman said Landrieu’s silence proves she has no interest in the scandal.

“Mary Landrieu hasn’t said a word about the missing emails and is sitting back rather than demanding answers,” said NRSC Press Secretary Brook Hougesen.“This is just another instance of Mary Landrieu putting her own political career above the well-being of Louisianians. Sen. Landrieu not only refuses to say whether she will return the contributions from the IRS Union, but she refuses to demand additional information from President Obama and the IRS about this deeply concerning scandal.”

And just as National Review notes, a number of computer whizzes are saying that the “lost” e-mails are actually somewhat impossible to loose.

A growing number of computer professionals are stepping forward to say that none of this makes sense. Norman Cillo, a former program manager at Microsoft, told The Blaze: “I don’t know of any e-mail administrator [who] doesn’t have at least three ways of getting that mail back. It’s either on the disks or it’s on a TAPE backup someplace on an archive server.” Bruce Webster, an IT expert with 30 years of experience consulting with dozens of private companies, seconds this opinion: “It would take a catastrophic mechanical failure for Lerner’s drive to suffer actual physical damage, but in any case, the FBI should be able to recover something. And the FBI and the Justice Department know it.”

Landrieu is just one of 13 Senators who has benefited from the IRS via donations through the IRS employees union. Her senate-challenger Rep. Bill Cassidy (R-LA) has previously signed onto a plan that would abolish the IRS entirely, saying “We need to replace the agency with something truly apolitical and limited in scope. Since there’ll be no IRS, the new entity will not have the mandate to enforce ObamaCare.”
