Governor Scott Walker takes another step toward presidential run

MADISON — Stepping closer to an all-but-inevitable White House bid, Wisconsin Gov. Scott Walker has created a "testing the waters" committee that allows him to raise money for a presidential campaign.

The two-term Republican governor has already been raising unlimited political donations through a tax-exempt group since January. And in April, former senior aides created a super PAC to bring in even more.

The new committee allows Walker to raise money for the first time that will be controlled exclusively by him and his prospective campaign.

In many ways, Walker has been testing the waters for most of the year. He has been assembling a large campaign staff based in Madison in addition to traveling the country extensively, with a focus on early presidential voting states such as Iowa and New Hampshire.
