Cable network pulls ad attacking Tester

HELENA (AP) — A conservative group's television advertisement has been pulled from a cable network amid complaints from U.S. Sen. Jon Tester that it falsely accuses him of supporting tougher rules for farm dust.

The ad from Crossroads GPS claims that Tester "voted against preventing Obama's EPA from being able to regulate Montana farmers' dust."

The Washington D.C.-based group says Cablevision's Optimum cable service did pull the advertisement, although other networks have not.

Tester's campaign argues the grain farmer has long record of opposition to the scuttled EPA proposal.

The ad bases its claim on a procedural vote to stop amendments on an unrelated bill, which Republicans later wanted to amend with a ban on farm dust regulations.

Tester is being challenged by Republican U.S. Rep. Denny Rehberg.
