Donald Trump refers to himself as 'daddy' in North Dakota

And Twitter isn't loving it...

Donald Trump quotes have a history of making the public squirm, with his Twitter feed essentially being one long inappropriate stream of thought.

During a recent visit to North Dakota where Trump delivered a speech on tax reform, he did it again, making the Internet cringe as he invited his daughter, Ivanka Trump, to the podium to say a few words.

‘She’s so good she wanted to make the trip,' he explained to the crowd. 'She actually said “Daddy can I go with you?”' he continued, before adding, ‘I like that.’

He continued: 'Everybody loves Ivanka - come up honey'.

While it's not too out of the ordinary for a father and daughter to have pet names for each other, people have been questioning whether it's appropriate for a senior White House advisor to speak in such a way to the president about official matters.

As we all remember, Trump raised eyebrows in March when he appointed Ivanka a key role in his administration, giving her a job that most politicians would only dream about, along with a West Wing office and classified information clearance.

Ivanka however didn't seem fazed at the North Dakota speech, announcing to the cheering crowd, 'Hi North Dakota, we love this state so it's always a pleasure to be back here. You treated us very very very well in November and have continued to, and we like showing the love back.'

Trump has a habit of hiring those closest to him, also hiring Ivanka's husband, real estate investor Jared Kushner, as his senior advisor, but it was Ivanka's position that the public called out as nepotism.

In response to the growing ethics concerns of her advising her father, Ivanka announced in a statement earlier this year:

‘I have heard the concerns some have with my advising the President in my personal capacity while voluntarily complying with all ethics rules and I will instead serve as an unpaid employee in the White House Office, subject to all of the same rules as other federal employees. Throughout this process I have been working closely and in good faith with the White House Counsel and my personal counsel to address the unprecedented nature of my role.’
