Vice President Joe Biden is expected to miss Israeli Prime Minister Benjamin Netanyahu's speech to a joint session of Congress next month, Biden's office said Friday.

The vice president's office said he is expected to be traveling abroad during the March 3 address, but it is not ready to announce details of the trip, which has been in the planning stages for some time, an official said.

House Speaker John Boehner's office announced last month that he had invited Netanyahu to address Congress without first consulting with the White House. The move enraged the Obama administration and strained ties between the two countries. Administration officials said the president would not meet with the prime minister, who is in the midst of a campaign.

“We want to avoid even the appearance of any kind interference with a democratic election,” White House Press Secretary Josh Earnest said last month.

High-ranking Democrats are considering boycotting the speech, calling the address an overtly political move ahead of the March 17 election.

Netanyahu will speak as many members of Congress are at odds with the administration over a bill that would impose new sanctions on Iran. The Israeli leader is expected to call for additional restrictions on the country.

Obama warned Congress last month that he would veto a sanctions bill, which he said would undermine diplomatic talks on the country's nuclear program and risk setting up a military confrontation.
