Wisconsin Gov. Scott Walker will headline House Republicans’ major fundraising dinner March 20.

Walker, who has been hailed as the conservative, collective-bargaining-busting hero, will deliver the keynote address at the National Republican Congressional Committee’s annual event at the National Building Museum.

Rep. Paul D. Ryan, R-Wis., chairman of the dinner, will work with Walker and other members on fundraising.

In 2012, South Carolina Gov. Nikki R. Haley headlined the dinner, which brought in a hefty $12 million.

The news of Walker headlining the dinner was first reported by Yahoo News.
