Two Democratic presidential candidates ā€” Massachusetts Sen. Elizabeth Warren and former Housing and Urban Development Secretary Julian Castro ā€” said President Donald Trump's decision Saturday to no longer hold next year's G7 summit at his golf resort in Florida doesn't go far enough to address corruption in his administration. 

Warren posted on Twitter: "The G7 may no longer be at Trump National Doral, but that won't stop foreign nations from dumping money into Donald Trump's pockets by spending at his hotels. And it won't stop Trump from rewarding Mar-a-Lago members with ambassadorships." 

Warren also added: "Trump is corruption in the flesh."

Democrats in the House of Representatives are currently investigating the allegation that foreign officials book rooms at Trump hotels in order to flatter the president. Trump has also frequently given ambassadorships to his campaign donors, a practice Warren has railed against. 

New York Jets owner Woody Johnson donated $1 million to Trump's inaugural committee and was nominated by Trump as the U.S. ambassador to Great Britain. U.S. ambassador to the EU Gordon Sondland also gave the same amount to Trump's inaugural committee, and was given his current position in return. 

"Trying to be a complete crook of a politician didn't quite work out for him this time, but Iā€™m sure he's not done trying. We need integrity back in the Oval Office," Castro tweeted. 

Trump's acting Chief of Staff Mick Mulvaney on Friday announced the decision to hold the G7 at Doral, while giving a press briefing with reporters. Mulvaney said that Trump would not profit from the event.

Critics believe that the move would violate the emoluments clause of the U.S. Constitution and would allow Trump to profit from the presidency. 

On Saturday night, Trump said that he would reverse the decision, citing "hostility" from the media and Democrats. He said the event might be held at Camp David instead, which is located in Maryland.

Mulvaney said Sunday that Trump "still considers himself to be in the hospitality business and he saw an opportunity to take the biggest leaders from around the world and he wanted to put on the absolute best show, the best visit that he possibly could, and he was very comfortable doing it at Doral." 

If Trump is interested in deal-making with foreign leaders, Camp David might be a much more appropriate choice. The venue has had a history of successful diplomacy, as it was where Egypt and Israel agreed on a framework for a future peace treaty, known as the Camp David Accords.
