MADISON, Wis. -

John Burke, the president of Trek Bicycle Corp. and the brother of Democratic gubernatorial candidate Mary Burke, is blasting Republican Gov. Scott Walker over his latest campaign ad.

John Burke issued a statement Thursday saying implications made in the ad are false. It was his most forceful and public statement on the race to date.

Walker released the ad on Wednesday. It blasts Wisconsin-based Trek for outsourcing jobs overseas to countries where workers are paid $2 an hour.

John Burke said he made the decision to get products for Trek outside the United States, not his sister. He said if he had not done that, Trek would not be able to employ 1,000 people in Wisconsin.

John Burke said what is particularly disappointing is Walker understands that.
