I happened to notice on Twitter this link to the fourth quarter congressional lobbying report by Koch Industries.

The billionaires’ company spent $2.46 MILLION in the FOURTH QUARTER. This doesn’t count the many and varied other Koch contributions to the likes of Americans for Prosperity and other political organizations.

Forest products (they own Georgia-Pacific), water resources (a lot of their businesses can produce discharges into waterways), the budget (they want lower spending and lower taxes), chemical industry regulation (no explanation needed) and energy legislation (they produce, ship and refine gas and oil) are among the interests listed. For more specifics, see Rep. Tom Cotton.
