Wisconsin Gov. Scott Walker has reportedly picked a chairman for his looming presidential campaign. Michael Grebe, the president of the Lynde and Harry Bradley Foundation in Milwaukee, is expected to be named Walker's campaign chairman, according to the Weekly Standard.

The Bradley Foundation supports conservative activism in Wisconsin and across the country, and has more than $600 million in assets, according to the Milwaukee Journal Sentinel.

Grebe has chaired the governor's previous gubernatorial campaigns, and his successful recall election. He is a veteran of the Vietnam War, and a lawyer with a long career in politics, including as a former general counsel for the Republican National Committee.

When interviewed by the Journal Sentinel in 2011 about the Bradley Foundation's activities, Grebe answered about the type of approach he favors to advance conservative politics.

"We're going to run off tackle, right over there, and we're telling you we're going to run there, and we're going to knock you on your butt and carry the ball down the field," he told the Journal Sentinel in 2011. "There are no surprises."

Walker's presidential campaign announcement is expected to come on Monday in Waukesha, Wis., where the governor celebrated his past electoral victories.
