Wisconsin Gov. Scott Walker (R) will keynote the National Republican Congressional Committee's annual fundraising dinner, The Hill has confirmed.

Walker is a favorite of movement conservatives for his successful battle against the state's unions, and some believe he may be interested in a presidential run. He'll join Rep. Paul Ryan (R-Wis.), a friend of his and the dinner's chairman.

The NRCC's annual March dinner is its largest fundraiser of the year, and it often brings in popular governors to help bolster its cause. South Carolina Gov. Nikki Haley (R) and New Jersey Gov. Chris Christie (R) are the previous two keynote speakers; both events raised more than $10 million for the group. The event is also a good chance for rising stars in the GOP to meet some of the party's most powerful donors.
