Wisconsin Gov. Scott Walker (R) is heading to Iowa, the latest signal he's preparing for a presidential bid.

Walker will attend a major conservative gathering organized by Rep. Steve King (R-Iowa) and Citizens United on Jan. 24.

The event will feature a number of Walker's potential primary rivals, including New Jersey Gov. Chris Christie (R), former Arkansas Gov. Mike Huckabee (R), Sen. Ted CruzRafael (Ted) Edward CruzGOP senators introduce Trump's plan to claw back billion in spending Pro-Trump super PAC raises .5 million in 6 weeks Trump has exposed Democratic hypocrisy on prison reform MORE (R-Texas), outgoing Texas Gov. Rick Perry (R), former Sen. Rick Santorum (R-Pa.) and former Hewlett-Packard CEO Carly Fiorina (R).

This is Walker's latest move toward a potential White House bid. He's also secured top GOP operative Rick Wiley to run his campaign, according to reports, and engaged in some tongue-in-cheek ribbing of Christie, making fun of his support of the Dallas Cowboys on Twitter earlier this week.
