Story highlights

Another member of the conservative House Freedom Caucus endorsed Ted Cruz on Tuesday

He continues to hold support from the group known for giving Republican leadership headaches

(CNN) —  

Another member of the conservative House Freedom Caucus endorsed Ted Cruz on Tuesday, as he continues to hold support from the group known for giving Republican leadership headaches.

Kansas Rep. Tim Huelskamp endorsed Cruz on Tuesday, the Texas senator’s rapid response director Brian Phillips tweeted.

“Ted Cruz is a full spectrum conservative that the people of Kansas should rally behind,” said Huelskamp in a statement.

Huelskamp’s endorsement makes 12 members of the Freedom Caucus that have supported Cruz, the most of the group behind any candidate, according to FiveThirtyEight’s endorsement tracker. A number of the lawmakers had endorsed Kentucky Sen. Rand Paul, another libertarian, anti-establishment Republican, who dropped out of the race after failing to gain momentum.

The group is known for causing trouble for House Republican leadership, especially during the reign of former House Speaker John Boehner. Their opposition was part of why Boehner stepped down from his role and resigned from Congress, and they also stood against his first heir apparent, Majority Leader Kevin McCarthy, causing the Californian to withdraw his name from contention and convincing now-Speaker Paul Ryan to run for the job.
