Companies are bringing in lobbying reinforcements from K Street in the wake of the Gulf oil spill and its legislative fallout.

BP hired the Eris Group to focus on environmental and energy issues, according to new documents filed Friday with the Senate. The firm — formerly known as Bartlett, Bendall & Kadesh — has two lobbyists working on behalf of BP with connections to lawmakers. Jennifer Bendall is linked to Sen. Richard Shelby (R-Ala.), and Jesse McCollum has ties to Reps. Edolphus Towns (D-N.Y.) and Ron Klein (D-Fla.).

Meanwhile, Anadarko Petroleum, which was named by the Environmental Protection Agency as potentially involved in the environmental disaster, has hired Hogan Lovells to work on “oil spill and energy legislation,” according to its lobbying disclosure filing. The firm, formerly known as Hogan & Hartson, filed papers Monday. A five-lobbyist team is working on environmental issues.
