Vice President Joe Biden is expected to miss Israeli Prime Minister Benjamin Netanyahu’s controversial address to a joint meeting of Congress because of foreign travel, Biden’s office said Friday.

The announcement comes amid deep White House irritation over Netanyahu’s decision to accept an invitation from House Speaker John Boehner, R-Ohio, without either party consulting the administration. The White House blasted the move as a breach of diplomatic protocol and said President Barack Obama would not meet with Netanyahu during next month’s visit.
