US President Trump says alleged links between his election campaign and Russia are a "hoax".

It's after grand jury subpoenas were issued over a June 2016 meeting between Donald Trump Junior and a Russian lawyer.

Trump has always denied any collusion with Moscow.

But back in May he left open the possibility that his staff may have been involved.

"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".
