LANSING, Mich. (AP) — Advocates of raising Michigan’s minimum wage pushed back Tuesday on a competing Republican bill to raise the wage, calling the measure “trickery” and saying it would silence voters.

Representatives of the Raise Michigan coalition said a bill introduced last week by Senate Majority Leader Randy Richardville, R-Monroe, would undermine their push to have voters decide whether to raise the minimum wage from $7.40 to $10.10 by 2017 through a ballot initiative. The campaign has collected more than the 258,000 signatures needed for a measure to appear on the November ballot to amend current law, spokeswoman Danielle Atkinson said.
