CNN and The Times have had their accusations proven to be false. Until there is clear evidence, it is very difficult for anyone to act, or anyone to form an opinion, Ben Harris-Quinney, chairman of the Bow Group think tank, told RT.

After meeting Russian President Vladimir Putin at the G20 summit, US President Donald Trump tweeted that, after a significant deal on Syria, it's time to move forward and work with Russia.

...We negotiated a ceasefire in parts of Syria which will save lives. Now it is time to move forward in working constructively with Russia! — Donald J. Trump (@realDonaldTrump) July 9, 2017

The US Ambassador to the United Nations, Nikki Haley, said in an interview with CNN that “everybody” knows Russia meddled in the US presidential election.

Following the summit, Trump also tweeted that he and the Russian president discussed the creation of a special working group on cyber security.

However, the idea was roundly criticized by many in the US establishment on the basis of Russia's alleged hacking activities.

There may be some areas of cyber security the US and Russia could make a partnership. Tackling ISIS - both abroad and in the West - would be the most obvious one

RT: When will solid, incontrovertible evidence be provided to back up these hacking allegations? Why hasn't it been so far?

Ben Harris-Quinney: I think as the President of the US Trump said: ‘The truth is that no one knows and although at least very few people know.” And very few people know because there has been no clear evidence on either side.’ What we do know, however, is the Trump administration is certainly concerned about the allegations that have been made, and it has caused some drag on the early days of the administration. We also know that many of the accusations have been disproved and major media networks, like CNN and The Times, have had their accusations proven to be false. Until there is clear evidence, it is very difficult for anyone to act, or anyone to form an opinion. The words of Nikki Haley that we’ve heard there – I think everyone’s very interested to learn what information that she has to back up those comments… If no evidence emerges, then I would imagine it would pass into history as an unsubstantiated claim.
