Congress included more than 100 earmarks in its fiscal year 2015 funding bills, despite having a moratorium on earmarks since fiscal year 2011. The number of earmarks fell in 2015, but the overall cost jumped to $4.2 billion, according to analysis by Citizens Against Government Waste.

The anti-government waste organization released its annual Congressional Pig Book on Wednesday, showing that earmarks are entering a new era in which they are fewer in number, higher in cost and less transparent.
