Coors Brewing Co. is to pull three ads from television screens in Colorado. The move follows chairman Peter Coors' announcement that he is to run for senator in the state.

The adverts feature Peter Coors being quizzed by Coors customers, with the tagline "You've got questions, we've got beer."

Coors said the adverts will continue to run over the rest of the US, but will not be shown in Colorado to comply with federal campaign laws.
