From the February 2, 2012 Wall Street Journal story on Lan Pham's firing:
"I was repeatedly pressured by the CBO Assistant Director, Deborah Lucas, in charge of the Financial Analysis Division to not write nor discuss issues in the banking sector and mortgage markets that might suggest weakness in these sectors and their consequences on the economy and households."
The CBO's 2010 termination letter to Ms. Pham cites her lack of qualifications, "poorly organized" research, and resistance to taking orders from her superiors as the reasons for her firing.

It is a little known fact, but probably no surprise to most, that in addition to not prosecuting any key participants in the financial fraud and crisis, the Obama Administration has instead been particularly tough on whistleblowers who expose government corruption.
