U.S. President Donald Trump and Russian President Vladimir Putin spoke for more than an hour on Friday, discussing the possibility of a new nuclear accord, North Korean denuclearization, Ukraine and the political situation in Venezuela, the White House said.

"Had a long and very good conversation with President Putin of Russia," Trump said in a post on Twitter, noting they had discussed trade, Venezuela, Ukraine, North Korea, nuclear arms and special counsel Robert Mueller's investigation of Russian meddling in the 2016 U.S. presidential campaign.

White House spokeswoman Sarah Huckabee Sanders told reporters Trump and Putin talked about the possibility of a new multilateral nuclear accord between the United States, Russia and China, or an extension of the current U.S.-Russia strategic nuclear treaty.
