A relatively small handful of federal contractors are responsible for the lion’s share of the $92 billion in fines, settlements, and court judgements assessed for defrauding taxpayers and other forms of contractor misconduct since 1995, according to a newly updated database published by the Project on Government Oversight (POGO).

An analysis by The Intercept finds that the companies responsible for the most instances of misconduct are also at the top of another list: They are among the biggest spenders on money in politics.

Boeing, an aircraft manufacturing firm that supplies the government with military equipment, has paid over $1.4 billion in penalties since 1995, according to POGO. Boeing’s misdeeds include overbilling the government on the KC-10 aerial refueling tanker, falsifying invoices, and an assortment of environmental crimes such as contaminating local waterways and spilling jet fuel. POGO has identified over 60 resolved instances of Boeing committing fraud or violating the law, topped only by Exxon Mobil, Lockheed Martin and BP.

But that doesn’t mean Boeing has fallen out of favor with lawmakers. Boeing spends a lot of money to make sure that doesn’t happen.

The firm ranks as the second biggest spender on lobbying Congress this year among individual companies — over $16 million for just the first nine months of 2015. Boeing also spent $1.9 million on campaign contributions to local and federal candidates last year. In addition, the company spends an undisclosed sum on trade associations, think tanks, television commercials, and billboards; public relations efforts; and political groups that use “dark money,” 501(c)(6) tax entities that influence elections without disclosing donor information.
