Colorado lawmakers have approved legislation that would block credit card companies from charging common "swipe fees" on sales taxes, a move that supporters argue would save businesses money. The bill passed the Senate’s Business, Labor and Technology Committee on a 3-2 party-line vote, with Democrats in favor. The move comes a year after lawmakers rejected a more expansive version of the proposal. Gov. Jared Polis' office has told lawmakers that he will delay his decision on whether to commute Tina Peters’ prison sentence until after a ruling by the Colorado Court of Appeals. The Colorado House passed pro-union legislation to make it easier for organized workers to negotiate with their employers, a rerun of a vetoed bill. The legislation would repeal a provision requiring a second vote before unions can begin negotiating with employers.
