President Trump on Monday asked Twitter users if his proposed summit with North Korean leader Kim Jong Un should take place on the border between North and South Korea.

"Numerous countries are being considered for the MEETING, but would Peace House/Freedom House, on the Border of North & South Korea, be a more Representative, Important and Lasting site than a third party country? Just asking," Trump tweeted.

Both Peace House and Freedom House are on the South Korean side of the border between the countries in the Demilitarized Zone.

The White House has yet to announce a date, time or location for the summit, but is expected to occur this month or next. Last week, Trump said they had narrowed to site list to two or three possibilities.

White House national security adviser John Bolton said Sunday that the administration is still working to choose an appropriate location.

“Well we need to agree on a place and that remains an issue,” Bolton told “Fox News Sunday.”

Bolton also told CBS News that the White House is looking at using Libya as an example of how North Korea could build trust with other nations.

"One thing that Libya did that led us to overcome our skepticism was that they allowed American and British observers into all their nuclear related sites. So it wasn't a question of relying on international mechanisms. We saw them in ways we had never seen before," Bolton said.

Kim met South Korean leader Moon Jae-in last week, becoming the first North Korean leader to touch South Korean soil since 1953. During the meeting, North Korea reportedly vowed to denuclearize the nation's test sites.
