"Rosie O'Donnell's disgusting, I mean, both inside and out. You take a look at her - she's a slob, she talks like a truck driver. Rosie is a loser," said Trump in an interview with the Entertainment Tonight show on CBS in 2006.
To be fair, Rosie started this feud. Earlier that year, after Donald decided not to strip Miss USA of her crown when she was caught underage drinking, O'Donnell criticised his ethical judgement. Quoting Trump in a silly, mocking voice on The View, she said "everyone deserves a second chance,” referring to Trump's statements on the issue and questioning his moral authority as a man with two divorces.
It all went downhill from there. "So, probably I'll sue her, because it would be fun. I'd like to take some money out of her fat ass pockets,” responded Trump. Did they ever bury the hatchet? No. Although he did wish her well after her heart attack in 2012, tweeting "get better fast. I'm starting to miss you!”
Rosie responded, "Well thank you Donald - I must admit your post was a bit of a shock, are you trying to kill me?"
Donald Trump infuriated many republicans when he took on a new target, John McCain. Trump said the Vietnam vet is no war hero and was met with an immediate, fierce reaction, when nearly every single republican in the race turned on him. However, Trump did not back down in this political firestorm.
In July 2015, at the Iowa Family Leadership meeting, Trump responded to a question about McCain, saying, "He's not a war hero.” "He's a war hero because he was captured. I like people that weren't captured, O.K.?”
In 2005, Donald Trump made vulgar remarks about women which happened to be recorded on a hot microphone. Trump told Billy Bush, from Access Hollywood, about his attempts at fornicating with a woman who remains unknown. Trump said he tried and failed because she put her marriage vows above him.
He said, "I moved on her like a bitch, but I couldn't get there. And she was married. Then all of a sudden I see her, she's now got the big phony tits and everything. She's totally changed her look." Commenting on how a man in his position can do whatever he wants, Trump said, "Grab them by the pussy. You can do anything.”
Trump made a statement saying the recording was "locker room banter.” However, he subsequently apologised for his disrespectful words and slammed Bill Clinton as the real sexual abuser in the political eye.
"This was locker room banter, a private conversation that took place many years ago. Bill Clinton has said far worse to me on the golf course - not even close. I apologize if anyone was offended," said Trump.
In the past, Trump called for building a list of all Muslims living in the US, and for surveillance over mosques. In the wake of the San Bernardino shooting in December 2015, he took it one step further, calling for a ban of all Muslims entering the US until officials can put a vetting process in place.
Reading from his campaign press release, Trump stated, "Donald J. Trump is calling for a total and complete shutdown of Muslims entering the United States until our country's representatives can figure out what the hell is going on. We have no choice." His proposal, although controversial, was welcomed enthusiastically by most of his supporters.
In his presidential announcement speech to the American public in 2015, Donald Trump denounced illegal Mexican immigrants as criminals and even rapists.
"The US has become a dumping ground for everybody else's problems. It's true. These aren't the best and the finest. When Mexico sends its people they're not sending their best. They're not sending you, they're not sending you,” he said, pointing to the crowd.
Trump continued, "They're sending people that have lots of problems and they're bringing those problems with them. They're bringing drugs, they're bringing crime, they're rapists. Some, I assume, are good people. But I speak to border guards and they tell us what we're getting and it only makes common sense. It only makes common sense. They're sending us not the right people.”
