There’s no telling what words were exchanged between U.S. Sen. John McCain (R-Ariz.) and liberal financier George Soros at the World Economic Forum in Davos, Switzerland.

But you can have a look at some photos of Thursday’s tete-a-tete:

What’s the connection between McCain and Soros?

According to The Huffington Post, in an article published during McCain’s 2008 presidential run, Soros funded the McCain’s Reform Institute, a nonpartisan 501c3 organization focused on promoting accountability and transparency in government, while the senator was still with the organization.

The Huffington Post article also referenced two Talking Points Memo reports: One indicated that Soros gave the Reform Institute $150,000; another said Soros’ Open Society Institute in 2002 gave $300,000 in grants to groups defending McCain’s campaign finance law against legal challenges to it.

Interestingly the Huffington Post article initially focuses on McCain’s campaign “aggressively” hitting back at news that Soros was taking part in a $40 million third-party effort to battle Republicans in the fall leading up to the elections.
