A part of Donald Trump believes Russia was behind the 2016 election hacking, but he also thinks that the interference was done by people from other countries. The president, during a news conference with Polish President Andrzej Duda, said no one really knows what happened and who's responsible for the U.S. election meddling.

"I think it was Russia but I think it was probably other people and or countries. I see nothing wrong with that statement. Nobody really knows. Nobody really knows for sure," he told the press. He went on and talked about reports on Iraq's alleged weapons of mass destruction which were proven wrong.

"Guess what? That led to one big mess. They were wrong and it led to a mess," he said as cited by CNN.

Trump slams Obama over election meddling

The incumbent U.S. president criticized his predecessor for allegedly doing "nothing" to stop the interference that has been causing tension on Capitol Hill. Barack Obama was reportedly informed by the Central Intelligence Agency (CIA) that Russia was behind the 2016 election hacking. Trump, however, insisted that the previous administration purposely ignored the issue since they were expecting that their bet, Hillary Clinton, would win the presidency.

But contrary to these statements, the former U.S. president has discussed the issue of interference with his Russian counterpart during their meeting at the G20 summit in China last year.

Obama even warned Vladimir Putin that they will face "serious consequences" if the election hacking will continue.

Media attacks

During his press conference with Duda, the U.S. president did not miss the chance to criticize the mainstream media which he labeled the "enemy" of the American people. Trump specifically targeted CNN and NBC over their coverage of certain issues.

He even returned to his argument that CNN is a "fake news" and claimed that the network is facing "some pretty serious problems" after sparring against him. Trump continued to accuse the news outlet of being "dishonest" about their coverage of his administration.

His remarks came after he uploaded a controversial video meant to attack the network.

The 28-second edited clip starred the U.S. president punching a man with CNN's logo on his face. The social media post has raised concern among his critics and supporters. Several members of the Republican Party even expressed their distress on the anti-media deemed to promote violence against journalists.
