OVERLAND PARK, Kan. (AP) - Former U.S. House Speaker Newt Gingrich is coming to Kansas to support the re-election campaign of Republican Sen. Pat Roberts.
Gingrich was scheduled to attend Friday afternoon's grand opening of Roberts' campaign office in Overland Park. The appearance comes a month after Leawood radiologist Milton Wolf announced that he'll challenge Roberts in next year's Republican primary.
Johnson County is a Republican stronghold and home to 21 percent of the state's registered voters, making it a key battleground.
Roberts' supporters see Gingrich's endorsement as helping the incumbent senator with the GOP's conservative base. Wolf is running as a tea party candidate and has criticized Roberts as a career politician.
Gingrich served as House speaker from 1995 to 1999 and ran for the Republican presidential nomination last year.
