Member of Kulanu and Israel's former ambassador in Washington Michael Oren has called for Prime Minister Benjamin Netanyahu to cancel his planned address to Congress.

"The behavior over the last few days created the impression of a cynical political move, and it could hurt our attempts to act against Iran," said Oren.

"It's advisable to cancel the speech to Congress so as not to cause a rift with the American government. Much responsibility and reasoned political behavior are needed to guard interests in the White House."
