US President Barack Obama will not meet with Prime Minister Benjamin Netanyahu when the Israeli leader travels to Washington in March, the White House has said.

Spokeswoman Bernadette Meehan said on Thursday that in keeping with "long-standing practice and principle," the president does not meet with heads of state or candidates in close proximity to their elections.

"Accordingly, the president will not be meeting with Prime Minister Netanyahu because of the proximity to the Israeli election, which is just two weeks after his planned address to the US Congress," Meehan said.

Netanyahu is scheduled to speak to Congress on March 3 and will push for additional sanctions on Iran.

He was initially scheduled to address politicians in February, but the date was changed so that it could coincide with Netanyahu's trip to Washington to address an annual conference held by AIPAC, the pro-Israel lobby group, in early March.

The invitation was a coordinated effort by House Speaker John Boehner and Senate Majority Leader Mitch McConnell, both Republicans, with staff discussions beginning last year, according to a senior Republican aide, who spoke only on condition of anonymity because he wasn't authorised to publicly discuss the private talks.

Boehner contacted the Israeli ambassador on January 8 to assess Netanyahu's interest and received a positive response.

The Republican leaders reached out to the Israelis without consulting with the White House or State Department, a move that appeared likely to deepen the White House's already tense relations with congressional Republicans as well as the Israeli leader.

Obama has been urging Republicans, as well as some members of his own party, to hold off on passing new Iran sanctions legislation while the US and international partners are in the midst of nuclear negotiations with the Islamic republic.

Netanyahu stands to gain politically at home from the US visit. He is in a tough fight to win re-election in Israel's upcoming March vote. Netanyahu's Likud Party is running behind the main opposition group headed by Yitzhak Herzog's Labor Party, which has been highlighting rancor in the country's critical relationship with the United States.

House Minority Leader Nancy Pelosi said it was inappropriate for Boehner to invite Netanyahu to address Congress in the shadow of the election and give the appearance of endorsing the prime minister.

"If that's the purpose of Prime Minister Netanyahu's visit two weeks before his own election, right in the midst of our negotiations, I just don't think it's appropriate and helpful," Pelosi said.
