Speaker Johnson pours cold water on eventual presidential run

"I don't think about that. No. I think this job, there's probably a reason I think there may be only one Speaker, James K. Polk, who became president after that, because the job is so all consuming and encompassing that it wears everybody out. I mean, look, I'll serve in any capacity I want, but I don't think about that. Never aspired to it. For that matter, I didn't aspire to this job."
