White House spokeswoman Sarah Huckabee Sanders said on Tuesday that President Donald Trump thinks talks with North Korea are going well and is prepared for a summit with Kim Jong Un to take place on June 12, as originally planned.

Sanders said denuclearization must be on the table for the summit to proceed as planned.

"We're going to be prepared if it takes place on June 12," Sanders said. "We'll certainly be prepared if it for some reason takes place at a later date — we'll be prepared for that as well."
