Soros has ties to Wiley that date back to the 1990s and last month he dropped $500,000 into an independent expenditure organization, 1199 for Maya, that backs Wiley's City Hall campaign.
The contribution was matched dollar for dollar by 1199SEIU, an influential healthcare workers union that has supported Wiley.
Most of the money will go towards a $1.2 million political advertising campaign in a last-ditch attempt to attract voters before the Democratic primary on June 22.

PACs can raise and spend endless funds yet cannot coordinate directly with the campaigns.
That legal distinction makes it possible for candidates to criticize independent expenditures, even as they profit from them.
Soros is often the object of criticism by Republicans for his outsize political influence.

'If we don't come together as a movement, we will get a New York City built by and for billionaires, and we need a city for and by working people,' stated democratic socialist Ocasio-Cortez, who represents parts of Queens and the Bronx. 'So we will vote for Maya #1.'

The massive sums given by Soros to the campaign are not yet reflected on the New York City Campaign Finance Board website which follows the flow of money in local politics.
'There is the belief that billionaires are bad for society — except for when they're giving to my campaign,' Doug Muzzio, a veteran political science professor at Baruch College, told the New York Post of the hypocrisy. 'That's the logic.'

Wiley has distanced herself from her financial supporters by stating she can't command who chooses to donate to her.
'I can't comment on independent expenditures because I've been very clear that I have no control over them,' she told the Post.

Wiley's links to Soros goes back to the late 1990s when she worked for The Open Society Foundations, founded by Soros. The non-profit is 'the world's largest private funder of independent groups working for justice, democratic governance, and human rights,' according to its website.
A few years later, in 2002, Wiley set up the Center for Social Inclusion which looks to 'end racial inequities through structural reform.'
