The Obama administration just loves watching the news. They like to watch TV, read the papers, listen to talk radio, etc. Since they're either completely detached from the actions of their own government or simply unwilling to acknowledge them, it's how they 'learn' about virtually everything they do.
I could run through the list of all the scandals they didn’t know about until they read about them in the paper but, by now, you know the deal. If the Obama gang has done something illegal, unethical, or unpopular, they learn about it "the same way you did."
So, how did the DOJ learn about Lois Lerner's lost emails?
According to Deputy Attorney General James Cole:
“I think we learned about it after that from the press accounts that were in the paper following the IRS’ notification to the Congress.”
