Obama and his minions have managed to politicize pretty much the entire government. They identify committed leftists like Lois Lerner and put them into important positions, from where they can act like soviet political commissars, monitoring the bureaucracy for anything potentially damaging or directing attacks on opponents.
There have been too many accounts of whistle blowers being shut down and retaliated against for it to be coincidence. Today's WashPost has a long article about a White house advance guy who was involved in the prostitute scandal in columbia. His father was a big donor and lobbyist. The DHS covered up his involvement, despite a lot of evidence. It infuriated the Secret Service, because several of their people got fired or censured over the same thing.
Basically, you cannot believe anything they say. They are all liars. It's hard to think of a single issue they haven't lied about, eg Fast and Furious, IRS, Benghazi, immigration, the economy, Obamacare, VA, now ebola.
