Elizabeth Warren held a swanky fundraiser at a winery in Boston in June 2018, new reports revealed over the weekend, raising questions over her criticism of her fellow Democratic presidential candidate's fundraiser at a wine cave.

Just a few months before announcing her candidacy for president – and about two years before she called out South Bend, Indiana Mayor Pete Buttigieg for his fundraiser – Warren held an event at City Winery Boston that gave the VIP experience to donors who gave $2,700.

'Billionaires in wine caves should not pick the next president of the United States,' Warren shot at Buttigieg during the sixth Democratic primary debate on Thursday in a reference to his fundraiser last weekend in Napa Valley, California.

'Think about who comes to that,' Warren continued of the 'wine cave' fundraiser. 'We made the decision many years ago that rich people in smoke-filled rooms would not pick the next president of the United States.'

'I do not sell access to my time,' she asserted.

While Buttigieg did hold the fundraiser where tickets went for $2,800 per head at a 'wine cave' in Napa Valley, California last weekend, Warren also held a winery fundraiser where VIP tickets went for donors who gave $2,700

The new revelations, however, show that Warren charged just $1,000 less for tickets to her winery fundraiser in 2018 than Buttigieg's $2,800 tickets a year-and-a-half later.

Warren's fundraiser featured a performance from singer Melissa Etheridge and offered souvenir wine bottles for $1,000 donors, Fox News reported, while bottles of wine at Buttigieg's campaign ran as high as $900.

Buttigieg called out Warren during the debate at Loyola Marymount University in Los Angeles, California, claiming – correctly, it now appears – that she wouldn't be able to pass her own purity test.

'Your presidential campaign right now as we speak is funded in part by money you transferred having raised it at those exact same big-ticket fundraisers you now denounce,' Buttigieg shot back. 'Did it corrupt you, Senator? Of course not,.'

'According to Forbes magazine, I am ... the only person on this stage who's not a millionaire or a billionaire,' Buttigieg said of the six other candidates who qualified for the December debate. 'This is the problem issuing purity tests you yourself cannot pass.'

Buttigieg also pointed out during the debate that he is the only candidate of the seven on stage who is not a millionaire or billionaire and challenged Warren to pass her own purity test before imposing it on others

Before announcing her candidacy in February this year, Warren also held several private meetings with wealthy donors to gauge their level of interest in supporting her run.

Buttigieg noted during their on-stage clash that the progressive Massachusetts senator also solicited funds from wealthy donors during her campaign for her Senate seat.

Tech entrepreneur Andrew Yang, the only minority candidate on stage Thursday, also took a hit at Buttigieg's Napa Valley fundraiser claiming presidential hopefuls shouldn't have to 'shake the money tree in the wine cave.'

If Buttigieg were to win the Democratic nomination he would become the first openly gay man to run on a major party ticket, and if he won the presidency he would be the first president to take office with student loans – which he and his husband have more than $100,000 in outstanding loans.
