Senate Leadership Fund, the super PAC affiliated with Senate Majority Leader John Thune, is coming off the sidelines in Texas' U.S. Senate race, placing its first ad buy of the general election in support of Ken Paxton.

Texas PAC, a new group connected to SLF, on Friday purchased an initial tranche of some $32 million worth of broadcast TV ads in the Dallas-Fort Worth, Houston, San Antonio and Austin media markets, according to the media tracking firm AdImpact.

Senate Republicans had been previously reluctant to spend money in Texas.
