LAREDO, Tex.

(KGNS) - House Speaker Mike Johnson campaigned in Laredo Thursday, August 27, the latest stop in a multi-city South Texas tour aimed at helping Republicans keep - and grow - their narrow majority in the U.S. House this November.

Johnson joined Webb County Judge Tano Tijerina to open Tijerina's campaign headquarters in the 28th Congressional District, where Tijerina, a Republican who switched parties, is challenging incumbent Democratic U.S. Rep. Henry Cuellar.
