Keep the Promise has a 30-second TV ad with Cruz that will air, starting Tuesday, for two weeks in Iowa through the Feb. 1 caucuses, according to the group. The ad launches in South Carolina next week, Jan. 25, and will run for nearly four weeks.

The ad includes video clips of Cruz from his speeches and remarks from his supporters arguing that the Texas lawmaker has stood up to Washington.

"When I tell you I'm going to do something, I'm going to do exactly what I said I would do!" a feisty Cruz says in one clip.
