One of President Donald Trump's more controversial pledges at his meeting with North Korean leader Kim Jong-un - that the United States would halt joint military exercises on the Korean Peninsula - touched off confusion on Capitol Hill as an influential GOP senator asserted the exercises would nonetheless continue.
Earlier, discussions took place on the possibility of President Moon Jae-in joining Kim and Trump in Singapore for follow-up talks on ending the war, but Moon was not invited.

Speaking at a news conference after the summit, he called the military drills "tremendously expensive".
While Washington has maintained that Pyongyang should achieve complete, verifiable and irreversible denuclearization (CVID) this was not included in the joint agreement between leaders at the summit.

The lone dissenting voice on the show was co-host Jessica Tarlov, who called it a missed opportunity that Trump didn't forcefully bring up North Korea's horrific human rights abuses.
Mr Trump and Mr Kim also promised to work towards building "a lasting and stable peace" on the Korean peninsula, and to repatriate remains of prisoners of war and those missing in action during the Korean War.
It appears follow-up talks to the North Korea-US summit will be essential, as the agreement reached on Tuesday on North Korea's denuclearization was made at a broad level without details.
There were plenty of smiles for the pair during the day.
"The North Koreans did not come with anything new", Hayden said on CNN.
