Eight challengers tossed their hat into the ring for last month's primary, resulting in both Pounds and Gooden falling short of the 50 percent of votes required to win the party's nomination.

Pounds received 12,895 votes, while Gooden received 17,501 out of the nearly 59,000 ballots cast.

Pence's endorsement adds to several heavy-hitter Republicans already backing Pounds's campaign, including Hensarling and House Freedom Caucus Chairman Rep.

Pounds has also been endorsed by the Club for Growth.

However, Gooden holds wide support in the area going into the runoff, as the 5th District covers his own 4th Texas state House District.
