Kansas congressman Tim Huelskamp says the next U.S. House speaker faces rebuilding the trust of his fellow conservatives.

Huelskamp said Friday in an interview that he hasn’t yet endorsed a candidate to replace outgoing Speaker John Boenher next month.

Huelskamp is a tea party favorite who represents the 1st District of western and central Kansas and has clashed with House GOP leaders.

Boehner late in 2012 stripped Huelskamp of seats on the House Budget and Agriculture committees. Until then, Kansas had a nearly automatic seat on the Agriculture Committee for decades.

Huelskamp remained critical of leading speaker candidate and Majority Leader Kevin McCarthy.

Huelskamp said he needs to see proof that a potential speaker will work with conservatives.

The congressman said, “They’ve got to rebuild some trust.”
