Senate Majority Leader Chuck Schumer (D-NY) said he felt obligated to attend Israeli Prime Minister Benjamin Netanyahu‘s joint address to Congress last week but did not feel it necessary to shake the leader’s hand.

“I went to this speech because the relationship between Israel and America is ironclad, and I wanted to show that,” Schumer said when asked why he did not shake Netanyahu’s hand in a Sunday interview with Robert Costa on CBS News’s Face the Nation. “But at the same time, as everyone knows, I have serious disagreements with the way Benjamin Netanyahu has conducted these policies.”
