His visit to Joplin came as President Donald Trump is continuing his tough talk against North Korea's nuclear ambitions.
It's all documented. With President Donald Trump, some people do think that his Twitter and overall personality could make a nuclear exchange more likely.
It comes on the same day Rodong Sinmun, the regime-run newspaper, warned the North would "surely win in the showdown" with the United States and South Korea.
"The weapons you are acquiring are not making you safer, they are putting your regime in grave danger", Trump said about North Korea during an address at South Korea's National Assembly in Seoul. "And do not try us".
"Together we have in our power to finally liberate this region and the world from this very serious nuclear menace, but it will require collective action, collective strength and collective devotion to winning the peace", Trump said.

Trump's visit to Beijing last week Xi reiterated that China would strive for the denuclearization of the Korean peninsula but offered no hint it would change tack on North Korea, with which it fought side by side in the 1950-53 Korean war against USA -led forces.
On Saturday, Kim's government responded by accusing Trump of trying to demonize North Korea, keep it apart from the global community and undermine its government.
"That might be a unusual thing to happen but it's a possibility", he said.
Nuclear-armed North Korea regularly denounces such military drills as rehearsals for invasion and sometimes conducts its own military manoeuvres or missile tests in response.
"Might be a odd thing to happen but it's certainly a possibility", Trump said during a press conference with Vietnam's president, adding that it would be "very, every nice if it did. I don't know if it will but it would be very, very nice".
This isn't the first time Trump and Kim have traded barbs.
In recent months, North Korea has tested intercontinental ballistic missiles that could reach the U.S. mainland with further development and has conducted its most powerful nuclear test.
