According to an Israeli newspaper, former White House chief of staff Rahm Emanuel, the current mayor of Chicago, blasted Israeli prime minister Benjamin Netanyahu for betting "on the wrong man" in the last presidential election. The allegation is that Netanyahu supported Mitt Romney in the election, and not the ultimate winner--President Barack Obama.
Yediot Aharonot reports (via the Blaze):
The tension between the prime minister and the American president is mounting. Rahm Emanuel, someone close to President Obama, over the weekend sharply attacked Netanyahu over his support for Mitt Romney and said: “This man Netanyahu bet on the wrong man – and lost.”
In fact, Netanyahu, despite knowing Romney for decades, did not endorse or explicitly support either presidential candidate.
