WASHINGTON (CBS NEWS) -- President Donald Trump and Defense Secretary Jim Mattis spoke on Saturday with their South Korean counterparts after the historic meeting between leaders of the two Koreas. Mr. Trump also said in a tweet Saturday morning that "things are going very well" as he prepares for an expected summit with the North's Kim Jong Un.
Mattis and Defense Minister Song Young-moo said they were committed to "a diplomatic resolution that achieves complete, verifiable and irreversible denuclearization" of the North, according to the Pentagon's chief spokeswoman, Dana W. White. Mattis also reaffirmed "the ironclad U.S. commitment" to defend its ally "using the full spectrum of U.S. capabilities."
Mr. Trump tweeted Saturday that he had "a long and very good talk" with President Moon Jae-in. He also said he updated Japan's prime minister, Shinzo Abe, about "the ongoing negotiations" for an anticipated summit with Kim, tentatively scheduled for May or early June.
