Billionaire left-wing mega-donor George Soros stated that former President Barack Obama was his “greatest disappointment” during an interview with the New York Times. The wide-ranging interview was largely based on his understanding that he’s losing big in the Trump era. Soros also used his time to praise Sen. John McCain (R-AZ), affirming his commitment to promoting bipartisanship.

His harsh statements about Barack Obama was based on around his belief that the former President “closed the door” on him after getting into office. Soros said he had great hopes that Obama would consult him on economic and financial issues, but that the President was more inclined to “woo his opponents” while taking his supporters for granted. Soros was a major supporter of Obama, giving millions to support his candidacy.

In the interview, the billionaire recalled the post-election phone call where Obama thanked him for his support, stating that it “was meant to last for five minutes,” but that he “dragged it out to eight minutes.”  That call was likely the moment that Soros realized that Obama only cares about himself, seeing him as nothing more than a tool to gain power.

But while much of Soros’ time was used to express his disappointment in Obama, he did have positive words to say about Sen. John McCain. He stated that he feels that the Republican party should reform itself and become more moderate, clearly seeing people like McCain as a positive influence towards that goal.

Soros also praised other moderate Republicans, specifically citing Sens. Lisa Murkoski (R-AK) and Susan Collins (R-ME). He even went so far as to state that he would be inclined to give them financial support before backing away from that statement, saying that his donation “would hurt them.”

George Soros is perhaps the most influential political donor on the left. Recently he spent millions of dollars to support Hillary Clinton’s 2016 presidential run, and has since then funded numerous “resistance” groups designed to stop President Donald Trump from implementing his agenda.

As for his future plans at the Presidential level, he was unsure what he would do, declining to say if he would back Bernie Sanders (I-VT) if he were to run. The only thing he made clear is that going forward, he will most likely become less influential to Democrats, stating: “I don’t particularly want to be a Democrat.”
