U.S. Rep. Blaine Luetkemeyer threw a bit of a curve to Missouri’s already crowded primary season when he announced he wouldn’t run for another term.

The St. Elizabeth Republican hasn’t been shy about expressing his disdain about high-profile infighting within his party, culminating in Kevin McCarthy’s ouster as speaker and a marathon melodrama to pick his replacement. But Luetkemeyer stressed his decision to retire after 16 years is based on a legitimate desire to stop working.

“I’m going to be 72 years old in May. And so people ask me about my health … is that the reason I'm retiring? I say: ‘No, my health is good. That's why I'm retiring,’” Luetkemeyer said in a wide-ranging interview.
