- Trump said he would be happy to debate Sanders before California primary
- Said it would get 'such high ratings' that money should go to charity
- Sanders replied 'Game on' and that he looks forward to debating Trump
- GOP frontrunner also once again admitted to using aliases in past business deals - but said he never pretended to be his own spokesman
- Also said he was merely being a 'good businessman' when he complimented Hillary Clinton in the past
Republican presidential candidate Donald Trump thinks Bernie Sanders would be easier to beat than Hillary Clinton in the November presidential election.
The GOP presidential hopeful admitted he thought Sanders was less competition when Jimmy Kimmel asked him if he liked the Vermont senator or Clinton better.
Trump then said he would be happy to debate Sanders in California, the last big primary battleground state before the party conventions, but only for a price.
'If I debated him, we would have such high ratings,' Trump said. 'And I think I should give, take that money and give it to some worthy charity. Okay?'
But Trump also took some time in the lengthy interview on the talk show host's ABC show to defend Sanders on what he called a 'rigged' system.
'What I like about Bernie, when he loses [it's] because the system is rigged against him like it was against me. The system is rigged.'
'And if I didn't win by massive landslides in every state, there was no chance for me to win. He's having the same thing, except she has a different kind of deal with superdelegates.'
'I think it's unfair what's happening to Bernie Sanders, actually,' he said. 'And it's a system that's not a good system.'
Sanders said on Twitter late Wednesday that he would welcome a debate: 'Game on. I look forward to debating Donald Trump in California before the June 7 primary.'
Kimmel also asked Trump about claims the presidential candidate pretended to be his own publicist in a recording that was recently released to the Washington Post.
Trump has repeatedly denied that he posed as a spokesman for himself during a People Magazine interview with the name 'John Miller', despite admitting multiple times in the past that he has often used both that name and 'John Barron' as an alias.
And when asked by Kimmel what aliases he had used, Trump once again volunteered the name Barron.
'I used an alias in terms of setting up a meeting with Mr Donald Trump. And many people in the real estate business do that, you use alias,' Trump said.
'And you have to, frankly, otherwise they find out it's you and they charge you more money - and nobody wants to pay more money.'
'Nobody knew who Trump was at that time, nobody knew me, so it wasn't so much so important. But I would never want to use my name because you had to pay money for the land. If you're trying to buy land, you use different names.'
Trump said he named his son Barron because he had landed a great business deal after using the alias to set it up.
It was business that the GOP frontrunner also used as an excuse when Kimmel questioned the compliments Trump had publicly paid to Clinton in the past.
'In 2008, you said you thought Hillary would make an excellent president,' Kimmel said, before bringing up that Trump had also said Clinton was 'terrific' in 2012.
'What happened?' Kimmel asked. 'What did she do?'
'I'll tell you. When I'm a businessman,' Trump offered as explanation. 'I speak well of everybody. If people ask me about politicians, I speak well. Everybody is wonderful. And that's the way it is.'
'So you were full of s***'? Kimmel asked.
'A little bit,' Trump said, laughing.
The extensive interview seemed to fill up the hole left by scheduled musical guests The Weeknd and rapper Belly, who canceled their performance on the late night show because of Trump's appearance.
Belly, who is Muslim, said he canceled because he didn't want to share a stage with Trump and disagrees with the presumptive Republican presidential nominee's views and beliefs.
'I feel like the way I was raised was to be able to see through all the titles in this world - from religion to race,' Belly said in a statement.
'I just didn't want to feel like I was a part of a celebration for somebody who has beliefs that majority of us don't agree with.'
Trump has called for a ban on Muslim immigration into the United States.
'For me, being Muslim and being somebody that appreciates my access here in America, I love the fact that I'm able to be here,' Belly continued.
'To play my part in this business is a privilege and a beautiful thing. The fact that I could lose that ability through the actions of someone such as Donald Trump isn't right to me. At all.'
