From PBS no less.
Here is the promo information:
One year ago, Expos? brought you "Mr. Heath Goes to Washington," about Seattle Times reporter David Heath's investigation of pork barrel politics. In the follow-up episode "Promises, Promises," Heath and colleague Christine Willmsen return to find -- despite the pledges made by a new Congress, calls for reform and a new law -- when it comes to pet spending projects, it's still politics as usual in Washington. This time the reporters unearthed at least 155 hidden earmarks worth $3.5 billion in the 2008 defense bill and found that in many cases, earmarks are actually more secretive than they once were.
