On Friday afternoon, Representative Denny Rehberg introduced a bold challenge that seems to one-up a similar challenge from the Tester campaign earlier this week. Rehberg's 'Made In Montana' pledge, which states that only contributions from Montana residents will be accepted by both campaigns, and that all monies from PACs and lobbyists be returned. That press conference with Rehberg campaign chairman Eric Iverson is attached.

Iverson would not comment on the similarities between Tester's challenge and the Rehberg 'Made in Montana' pledge. There has been no word from the Tester campaign yet on Rehberg's challenge.
