Visiting senior US senators told their Israelis hosts on Sunday that they disapprove of the Obama Administration's attempt to pressure Israel by threatening to withhold aid, and vowed they would never let that happen.

Senator John McCain told a Jerusalem press conference that he expects President Barack Obama to explicitly announce that his administration is not planning to alter America's policy regarding financial aid to Israel.

Senator Joe Lieberman promised that even if Obama did try to use US financial aid as leverage, Congress would never approve such a measure.

McCain and Lieberman were also joined by senators John Thune and John Barrasso.

The visit by the senior and powerful lawmakers came just days after Obama's special Middle East envoy George Mitchell caused a diplomatic storm by suggesting in an interview with Charlie Rose that the US may withhold financial aid if Israel did not meet more Arab demands.
