From the Washington Times over a month ago:
'EPA officials told the committee they were unable to provide a number of relevant documents because Mr. North’s computer crashed in 2010 and his files were not backed up on an EPA server,” Ms. Carroll said. “Because critical documents are missing, only Mr. North can answer many of the committee’s remaining questions, however, he has gone to great lengths to avoid cooperating with the committee.”'
I suppose that people are ok with government impropriety if they find the outcome to their liking.
But if one takes issue with emails being "lost" in ONE government agency to cover up wrong doing... one should be equally outraged with it happening in another.
