CHICAGO (MCT) — House Majority Leader Eric Cantor’s decision to weigh in on a contested Illinois primary involving two Republican incumbents is creating tensions in the House GOP caucus in Washington.

Cantor, R-Va., disclosed late last week that he made a $25,000 contribution to a super political action committee, the Campaign for Primary Accountability, to help first-term Republican Rep. Adam Kinzinger of Manteno defeat 20-year GOP incumbent Rep. Donald Manzullo of Leaf River. The two matched up in a primary in the new 16th District because of a Democratic-drawn redistricting map.
