this war has to be the longest war, almost 70 years. can you believe we're talking about the ending of the korean war? >> the announcement coming after talking with vice chairman kim yong choi after over an hour. president trump surprising some when asked about receiving a letter from kim jong-un. >> i haven't seen the letter yet. i purposely didn't open the letter. i haven't opened it. i didn't open it in front of the director. i said would you want me to open it? he said you can read it later. i may be in for a big surprise, folks. >> the president has since read the letter, i don't know if it was a big surprise, but that happened during the daily briefing, my favorite part, when he made that joke. an amazing day, i think that the big news kimberly is that, yes, of course the summit is a go, at least today, we'll see how that goes next week. but also, the south koreans have been pushing for this possibility of signing an end to the korean war.
