Former New York Mayor Ed Koch expressed disappointment in President Obama on Thursday for his treatment of Israel after it announced it would continue construction in East Jerusalem – the section of the holy city claimed by the Palestinians.

"I have been a supporter of President Obama and went to Florida for him, urged Jews all over the country to vote for him saying that he would be just as good as John McCain on the security of Israel. I don't think it's true anymore," Koch told Fox News' Neil Cavuto.

Israeli Prime Minister Benjamin Netanyahu got a chilly reception at the White House last week after Israel announced plans to build 1,600 new apartments for Jews in East Jerusalem during a visit from Vice President Biden. The announcement drew sharp condemnations from Washington and calls to cancel the construction plans – requests that Netanyahu says he will not heed.

Koch said he believes Obama "orchestrated" what happened in Israel.

"What they did is they wanted to make Israel into a pariah," he said. "It's outrageous in my judgment. "
