'The man is a sexual predator': Derryn Hinch slams Pauline Hanson over her sympathy for Donald Trump's lewd comments in the 'grab them by the p***y' video

Controversial Senators Derryn Hinch and Pauline Hanson have been involved in a heated argument in the corridors of Parliament House, after the One Nation leader sympathised with Donald Trump over his much-publicised sexist remarks.

Appearing on their usual segment on Sunrise on Monday morning, Hinch and Hanson failed to see eye-to-eye over the topic of Trump and the US election.

But it was off screen where their debate really heated up, with Senator Hinch lambasting his parliamentary colleague for her support of Trump as the pair walked away from the interview together.

'That you as a woman could even make justification for what he has said and what he has done is…,' Senator Hinch said, so furious he was unable to finish his sentence.

Senators Derryn Hinch and Pauline Hanson have been caught having a heated argument in the corridors of Parliament House in Canberra after debating whether Donald Trump should remain in the US Presidential race

Senator Hinch slammed the One Nation leader over her comments on Channel Seven's Sunrise in which she sympathised with Trump over lude remarks he made about seducing women

Senator Hanson was visibly taken aback by the attack, but instantly defended her comments.

'Well I didn't condone what he (Trump) said,' replied Senator Hanson.

But Senator Hinch wasn't done, going on the attack again and saying: 'The man is a sexual predator and he's a disgrace.' 

The debate between the two Senators came in the wake of revelations that in 2005 Trump made lewd comments about how he seduced women.

'You can do anything. Grab them by the p***y,' Trump reportedly said, which has led to many - including Senator Hinch - to call for him to drop out of the Presidential race.

But on Monday, Senator Hanson sympathised with Trump, saying that his comments weren't overly unusual for 'men'.

'It's up to the people, what he said was vulgar I don't support it whatsoever (but) it was said off camera, it was said behind the scenes and it was a tape recording,' she said.

'Now let's be honest about it, there are a lot of men out there they say horrific things, probably up to the same standard (behind women's backs).'

Senator Hanson defended Trump's comments, saying that 'there are a lot of men out there they say horrific things'. That statement outraged Senator Hinch, who lambasted his colleague over her views

Trump reportedly said that when seducing women, 'you can do anything. Grab them by the p***y.'

At that point an outraged Senator Hinch interjected.

'No way Pauline, I can't let you get away with that,' he said.

'A normal man in a private conversation would not talk about this. A normal man would never consider invading a woman's space so much that in his mind or to his mates would say (this) - that is sexual assault.' 

Senator Hanson said the decision should be left with the American people, but Hinch wasn't as philosophical about Trump as the future leader of the free world.

'Pauline, god help us if you are right, the man is a sexual predator,' Hinch said.
