President Barack Obama tried to reassure his worried Jewish supporters that his administration is committed to Israel’s security, The Associated Press reported on Wednesday.

According to the report, Obama told the supporters, “We don’t compromise when it comes to Israel’s security.”

Obama made the comments while speaking to a group of campaign contributors at the Upper East Side home of Jack Rosen, a prominent businessman and chairman of the American Jewish Congress.

The President responded after Rosen mentioned “concerns” within the Jewish community about the U.S.-Israeli relationship, AP noted. These concerns, it was felt, might affect campaign contributions from prominent Jewish supporters.

Rosen told the news agency that he felt that America has never been as supportive of Israel’s security as it has been under Obama, and noted that Obama said no ally is more important than the state of Israel.

Obama came under fire this year for his policy on Israel, particularly after his foreign policy speech in May, in which he called for a return to the 1949 armistice lines (often erroneously called 1967 borders)  as a starting point for negotiations with the Palestinian Authority.

The speech drew criticism from Obama’s political opponents, with Republican presidential hopeful Mitt Romney accusing the President of having “thrown Israel under the bus.”

Another Republican presidential hopeful, Rick Perry, later said Obama is at fault for the Palestinian Authority turning to the UN to achieve statehood. Perry described Obama’s Middle East policy as being “naive and arrogant, misguided and dangerous.”

Even New York State Assemblyman Dov Hikind, a member of Obama’s Democratic party, has criticized the President’s policy on Israel.

“There are many many issues, and I’m concerned about all the issues, but you can’t be right on everything and wrong on Israel,” he said. “We will not support you if you’re wrong on Israel.”
