Vice President Joe Biden said Monday that the Obama administration is feeling “overwhelming frustration” with Israel and Prime Minister Benjamin Netanyahu’s push to expand Jewish settlements.

“We have an overwhelming obligation, notwithstanding our sometimes overwhelming frustration with the Israeli government, to push them as hard as we can toward what they know in their gut is the only ultimate solution, a two-state solution, while at the same time be an absolute guarantor of their security,” Biden said to the J Street lobby group annual gala dinner in Washington Monday night.
