WICHITA, Kan. (AP) — President-elect Donald’s Trump’s nomination of U.S. Rep. Mike Pompeo for the top CIA job would put up for grabs the congressional seat in the south-central district.

Pompeo says in a statement that he is “honored and humbled” to accept the nomination, calling the decision to leave his congressional seat difficult. He says the opportunity to lead the CIA is a call to service he could not ignore.

Before starting the job, Pompeo would have to be confirmed by the Senate.

Pompeo was elected to the 4th District congressional seat during the tea party wave of 2010, and easily won re-election this month.

A special election would be required to fill the post. There is no primary.
