No one involved said Beck did anything more than display the pump

Garten claims it was because she appeared 'to do it in the middle of the deposition'

Trump's lawyer Alan Garten said the comment was not in regards to Beck's 'decision to breast-feed or pump'

Donald Trump once told lawyer Elizabeth Beth 'you're disgusting' after she asked for a medical break in court to pump breast milk for her infant daughter

Donald Trump once told a lawyer she was 'disgusting' and demanded a deposition continue after she asked for a court break to pump breast milk for her 3-month-old daughter.

Trump was testifying in a lawsuit over a failed Florida real estate project when Elizabeth Beck, pulling out the pump and said a medical break was urgent.

The Republican presidential candidate does not dispute that he told told Beck 'you're disgusting' before walking out of the room.

Trump had previously told Beck during the 2011 deposition that her questions were 'very stupid', according to testimony drawn from a series of lawsuits since 2007 and obtained by the New York Times.

He had also asked her, 'Do you even know what you're doing?'

Beck's clients had alleged they lost tens of thousands of dollars after forfeiting down payments on a real estate project gone bust for a building that his name was attached to.

The lawyer's husband, who was co-counsel on the case, said Trump also called Beck 'uptight' and said he had a 'meltdown' when his wife asked for the hour-long break.

Alan Garten, a lawyer for Trump, said his client's language - which he did not dispute - was not in regards to Beck's 'decision to breast-feed or pump'.

Garten claims that it was instead based on the fact Beck 'was appearing to do it in the middle of the deposition', although neither side said the lawyer had done anything more than display the pump.

Trump's lawyer went on to claim he had never seen 'more bizarre behavior' than Beck's at a deposition in his 20 years of legal practice.

'That is what led to his remark,' Garten told the New York Times.

Garten also said he believed Beck had been trying to buy time to think of more questions to ask Trump and claims 'every accommodation' was made to allow her medical breaks.

Trump told the Becks they should be congratulating their clients, who he said were 'very lucky' and claimed they would have actually lost more money if the project had gone through following the 2008 financial crisis.

The Becks lost one of their cases against Trump. They are currently appealing.
