Hatch also introduced a resolution designed to reaffirm U.S. support for Israel's borders to be based on the territory it gained in the 1967 war against several Arab states. 

"It is contrary to United States policy and our national security to have the borders of Israel return to the armistice lines that existed on June 4, 1967," the resolution states. 

In comments on the Senate floor, Hatch said the resolution "removes any harmful ambiguity the president’s remarks might have caused." 

Obama came under criticism from members of both parties when he said a peace deal should include 1967 borders plus mutual "land swaps" in a major address on the Middle East. The White House argued Obama was not saying anything new and that negotiated land swaps could broaden Israel's territory to include new settlements and land Israel's government contends is vital to its security. 

Israeli Prime Minister Benjamin Netanyahu told the U.S. Congress later in the month that such borders would render Israel indefensible.

According to Hatch, the resolution, which has bipartisan support, will reaffirm "our nation’s steadfast and unshakable commitment to the security of Israel, specifically through the establishment of secure, recognized, and defensible borders."
