Four North Carolina Republicans have sworn off federal earmarks.
Sen. Richard Burr and Reps. Patrick McHenry, Virginia Foxx and Walter Jones agreed not to ask for specific spending projects in federal bills when contacted by the conservative Club for Growth.
They are among six senators and 17 representatives who pledged to "swear off pork," in the words of the Club for Growth.
All four agreed to a similar pledge in 2008.
