Sen. John McCainJohn McCainTrump wall faces skepticism on border No Congress members along Mexico border support funding Trump's wall Treasury won’t grant Exxon drilling waiver for Russia MORE (R-Ariz.) said Sunday that the relationship between the U.S. and Israel has hit a new bottom under President Obama.
"It's the worst that I've ever seen in my lifetime," McCain said on CNN's "State of the Union."
McCain acknowledged the relationship was also strained under former President George H.W. Bush, but said "no one other president has had such a difficult relationship with Israel."
"The president had very unrealistic expectations about the degree of cooperation that he would get from Israel," he said, on the issues of a Palestinian state and an Iran nuclear negotiations.
"They've never been excellent, but they've never been worse," McCain added.
Tensions between Israel and the White House erupted after Israeli Prime Minister Benjamin Netanyahu accepted Speaker John Boehner's (R-Ohio) invitation to address Congress in March on the threat of Iran. Boehner did not discuss the invitation with the White House.
McCain said he would have given administration officials some notice, but that it was "not surprising" given the way relations are between the president, Boehner and Senate Majority Leader Mitch McConnell (R-Ky.)
"Obviously I would have talked to the White House....I might have at least informed them, but I certainly agree we don't need their permission given the state of relations," he said.
"Obviously, we'd want everyone to work together," McCain said. "The Speaker felt the overriding concern was to have him appear before the American people," he added.
