Topeka ? Kansas Reps. Jerry Moran and Todd Tiahrt have joined the new Tea Party Caucus in the U.S. House.

Tiahrt and Moran are seeking the Republican nomination for U.S. Senate in the Aug. 3 primary. Both have been running to the right — and courting tea party movement members.

Tiahrt has represented the 4th Congressional District of south-central Kansas since 1995. Moran has held the seat for the 1st District of western and central Kansas since 1997.

Rep. Lynn Jenkins, a Republican who represents the 2nd District of eastern Kansas, also joined the caucus after Moran and Tiahrt.

The caucus was formed by Minnesota Rep. Michelle Bachmann, a Republican who’s become a tea party favorite.
