"I would rather not get into the specifics on that", he said.
The US side has included North Korea's chemical and biological weapons in the negotiations with Pyongyang. I've been doing this since the first Bush administration, George H.W. Bush. "I'm not going to speculate on what that particular commercial satellite picture shows".
There have also been reports from South Korea's intelligence service of new activity at a factory at Sanumdong near Pyongyang that produced North Korea's first intercontinental ballistic missiles capable of reaching the United States.
Bolton told Raddatz that Trump is "open to a third summit" with Kim but that nothing has been scheduled.
The president has been very clear that he doesn't want to make the same mistakes as past administrations, Bolton said.
Bolton told ABC that he was not aware of any contact between the U.S. and North Korea since Vietnam, though it was "possible the South Koreans have spoken to North Korea".

The state-run Korean Central News Agency reported Sunday that newspapers, including North Korea's most influential daily, called on citizens to take part in the election. When Raddatz asked about Trump's comment that he would be surprised if Kim Jong-un did anything that was not consistent with their understanding, Bolton acknowledged that he would not react the same way.
"What can you tell us?" The site was dismantled in an apparent show of goodwill after Trump's first summit with Kim in June and the US president said he would be "very disappointed" if it was being rebuilt.
"Diplomacy is still very much alive", Biegun said, although he offered no specifics on when new talks might be held and did not say whether any talks had taken place since the summit, which collapsed over differences on USA demands for Pyongyang's denuclearization and North Korea's demand for sanctions relief.
Instead of a missile test, North Korea might say it was launching a rocket to deliver a satellite into space.
