(Newser) – President Trump is in Poland, where he gave his first press conference of the trip Thursday alongside Polish President Andrzej Duda, covering a wide range of topics including natural gas, Russian election meddling, North Korea—and "fake news." Asked about interference in the 2016 election, Trump declined to give a yes-or-no answer on whether he thought other countries were involved, reports the New York Times. "I think it was Russia, and it could have been other people in other countries," he said. "Nobody really knows," he added, noting that US intelligence agencies have been wrong before, including before the 2003 invasion of Iraq.

Speaking at Warsaw Castle, Trump also said North Korea will face consequences for its "very bad behavior," the BBC reports. "I have some pretty severe things that we're thinking about," he said. He also praised the strong alliance between the US and Poland. Duda, who has had his own problems with the media, nodded as Trump denounced "fake news" in response to a question about CNN. "NBC is nearly as bad, despite the fact that I made them a lot of money on The Apprentice," Trump said. Reuters reports that Trump is due to deliver a speech in Warsaw later Thursday in which he will condemn "the steady creep of government bureaucracy," according to excerpts released by the White House.
