TOPEKA, Kan. (AP) — A national Republican group has contributed $45,400 to Kansas Sen. Pat Roberts in his GOP primary race against tea party challenger Milton Wolf.
The donation from the National Republican Senatorial Committee helped Roberts raise more than $200,000 so far this month.
Finance reports filed by the campaigns showed that Wolf raised more than $120,000 in contributions this month and also loaned his campaign an additional $20,000. Wolf is a Leawood radiologist making his first run for public office.
Roberts is seeking this fourth, six-year term and has enjoyed a significant fundraising advantage ahead of the Aug. 5 primary.
He’s raised about $3.4 million since the beginning of last year. Wolf formally entered the race in October and saw his total contributions top $1 million this month.
