Aides to Hillary Clinton wanted her to appear at a fundraiser supported by George Soros because they believed this would be a good way for the Democratic presidential nominee to 'make him happy,' according to hacked emails revealed by WikiLeaks.

The new revelations shed light on the degree to which Soros, the 85-year-old Hungarian-born billionaire and mega-donor to the Democratic Party, had Clinton's ear.

On October 7, 2014, a top Clinton aide, Huma Abedin, wrote an email to Robby Mook, who would eventually go on to run Clinton's campaign.

Abedin informed Mook that Clinton was having dinner with Soros.

The aide wrote that she anticipated Soros would ask Clinton to appear at a fundraiser for America Votes, a progressive organization that he backs.

Abedin asked Mook how to proceed, to which he replied: 'I would only do this for political reasons (ie to make Soros happy).'

For the past couple of weeks, WikiLeaks has been releasing masses of emails from the hacked account of John Podesta, the most senior operative running the Clinton campaign.

Podesta is also closely tied to Soros.

The WikiLeaks emails show that Soros' top aides routinely communicated with Podesta, conveying the billionaire's positions on issues ranging from trade to immigration to the Supreme Court.

The emails reveal that Soros aides authored policy papers that reflect their bosses' thinking on a number of issues – and those positions were then shared with Podesta and the Clinton camp.

'In general I think George is more interested in talking about policy than the campaign per se,' Michael Vachon, an advisor and spokesman for Soros, wrote to Podesta on March 7, 2016.

'In a separate email I will send you George's latest thinking on the migration crisis, which he is spending a lot of time on. His other big preoccupation these days is Ukraine.'

Soros' aide would also make sure that the Clinton camp knew of his boss' position on issues like climate change and the Trans Pacific Partnership.

The emails potentially reinforce the perception that Clinton is beholden to deep-pocketed donors, and that those ties could have an undue influence on the policies that she will promote if and when she enters the White House.

The revelations were the latest gleaned from the hacked email account of John Podesta (above), the chairman of Clinton's presidential campaign who also has ties to Soros

Earlier this week, it was learned that Soros is one of five mega-donors who are responsible for one in every $17 dollars that have been spent on Clinton's presidential campaign.

The Clinton campaign proper and SuperPAC Priorities USA had raised a combined $1.14 billion by the end of September, filling their coffers to the brim with the help of the Democratic candidate's wealthy friends and national labor unions.

A Washington Post assessment of Clinton's fundraising found that a fifth of the money that went to her campaign directly or was donated through her joint fundraising committee, the nominating convention host committee, her PACs and the Democratic Party came from 100 individuals or unions.

Major donors to her bid included hedge fund manager Donald Sussman, who donated $20.6 million and investor J.B. Pritzker, whose sister is the current Secretary of Commerce, and his wife, M.K.. The Pritzkers were responsible for $16.7 million; in donations.

Univision chairman Haim Saban and his wife Cheryl gave $11.9 million, while Soros wrote checks in the amount of $9.9 million.
