Espionage is a sensitive subject between Israel and the U.S. because of the Pollard affair.
Pollard, a former civilian intelligence analyst, was sentenced to life in prison in 1987 for passing classified material to Israel.
Israeli leaders frequently call for his release and say his nearly three decades in prison are punishment enough, but stiff opposition from the American military and intelligence community has deterred a string of American presidents from releasing him.
Since Pollard's conviction, Israel has promised not to spy on the U.S. Ministers stressed Sunday that Israel does not spy on the U.S. president or defense secretary.
“I think we should expect the same relations from the U.S.,” Steinitz said.
Prime Minister Benjamin Netanyahu issued a more subdued reaction, saying that Israel continues to press for the convicted spy's release.
“This is not conditional and not connected to the latest events, even though we gave our opinion about these developments,” Netanyahu told his Cabinet, presumably referring to the reported U.S. spying.
