Republican presidential nominee Donald Trump has taken to Russian TV to not only criticise the foreign policies of Barack Obama but also of his predecessor, Republican president George Bush.

Speaking to Larry King on Russia Today about the war in Iraq, Trump said: "It's a war we shouldn't have been in, number one. And it's a war that, when we got out, we got out the wrong way. That's Obama."

Both Trump and his running mate, Mike Pence, have hailed the Russian president as a stronger leader than Obama, leading Hillary Clinton to label such remarks as "unpatriotic and insulting".

At last night's forum, Trump disrespected our generals, our country, and women in the military—but he praised Putin. pic.twitter.com/I08j5ap1DX
