MADISON, Wis. -

Gov. Scott Walker is taking the unusual step of sending a public letter to Assembly Speaker Robin Vos encouraging the fellow Republican to work on finding a solution to roads funding.

Walker released his letter to Vos on Wednesday.

In it, Walker defends his call not to raise taxes or fees to pay for roads.

Vos and other Republican Assembly leaders last week criticized Walker's approach, saying delaying major projects and borrowing more money is a political solution that doesn't address the long-term transportation funding ``crisis.''

Walker says in the letter that ``Republican leadership should stand with the taxpayer.''

He says he's willing to consider alternatives, but ``we can agree that we did not get elected as conservatives to raise taxes or fees.''
