The White House says it is delaying the next summit between President Donald Trump and Russian President Vladimir Putin until next year. Trump had invited Putin to the White House this autumn. The announcement came after a series of mixed messages about the US position on Russia and just ahead of a public foreign policy hearing with America's top diplomat. CGTN White House Correspondent, Jessica Stone reports.

Four days after the leaders of Russia and the United States met behind closed doors, US President Donald Trump ordered his national security advisor to set up a second meeting slated for this fall.

The offer took the nation's director of national intelligence by surprise -- only to be reversed, Wednesday, when National security advisor John Bolton said via statement -- the meeting would be delayed until next year. Even members of Trump's own party say they're concerned.

BOB CORKER US SENATOR "You come before a group of senators today who are filled with serious doubts about this White House and its conduct of American foreign policy."

Wednesday, U.S. Secretary of State Mike Pompeo tried to reassure lawmakers that Trump had fully debriefed him on the two hours plus conversation he held with Putin -- behind closed doors.

Pompeo said both he and Trump warned Moscow against meddling in the 2018 U.S. elections, adding Trump had NOT offered to lighten sanctions or allow Moscow to interrogate former U.S. diplomats. Pompeo also clarified Washington's position on Crimea.

MIKE POMPEO US SECRETARY OF STATE "We stand together with our allies, partners and the international community in our commitment to Ukraine and its territorial integrity."

And when it comes to making progress on the Korean peninsula nuclear issue. Pompeo said Pyongyang's dismantling of this satellite launching station captured here is promise kept by Kim Jong Un. But he also admitted, the Democratic People's Republic of Korea is still producing material for nuclear weapons.

ED MARKEY US SENATOR "I'm afraid that the Trump administration is being taken for a ride."

MIKE POMPEO US SECRETARY OF STATE "We have no intention of letting the world's sanctions that we led the charge to be put in place -- be lifted or not enforced -- until such time as chairman Kim makes good on the commitment he made which I am incredibly hopeful that he will, those sanctions will remain. We have not been taken for a ride."

JESSICA STONE WASHINGTON "The top US envoy on the DPRK heads back to the region this week to continue talks on denuclearization. Secretary Pompeo heads to Singapore next week, Jessica Stone, CGTN Washington."
