US President Donald Trump says concerns about his election campaign's links with Russia are a "total fabrication" and a "hoax".
It comes as grand jury subpoenas were reportedly issued in connection with a June 2016 meeting - involving his son Donald Trump Jr, son-in-law Jared Kushner and a Russian lawyer.
Moscow has denied any involvement and Mr Trump has repeatedly denied collusion by his campaign team.
Back in May, he said the investigations were political witch hunts.
"The entire thing has been a witch hunt and there is no collusion between certainly myself and my campaign.
"But I can only speak for myself and the Russians - zero.
"I think it divides the country, I think we have a very divided country because of that and many other things".
