Former Justice Minister MK Tzipi Livni on Sunday evening weighed in on the ad in the New York Times which accused President Barack Obama’s National Security Adviser Susan Rice of ignoring genocide.

The ad, which appeared in Saturday’s New York Times, was taken out by well-known pro-Israel advocate Rabbi Shmuley Boteach, and was denounced by a host of Jewish organizations in the United States.

In a post on her Facebook page, Livni linked between Prime Minister Binyamin Netanyahu’s upcoming Congress speech and the ad which, she claimed, was funded by people close to Netanyahu.

“We cannot be indifferent. The relations with the United States are integral to Israel’s security, and harming these relations hurts Israel’s security,” she warned.

“The ad against national security adviser Susan Rice, published in the New York Times which was funded by her political opponents and those close to Netanyahu, is despicable, vile and crosses red lines, and especially – it reflects the murky atmosphere created in the United States thanks to Netanyahu’s ‘generosity,’” Livni continued.

“Netanyahu, by politically sneaking into Congress for a speech, turned the U.S.-Israel relationship into a partisan issue that is harmful to Israel and its security. Netanyahu is selling our relations with our closest ally for a campaign speech and for his political survival,” she charged.

The ad in the New York Times appeared to be a reaction to comments Rice made in a recent interview with Charlie Rose, where she argued Prime Minister Binyamin Netanyahu’s speech before Congress could be disastrous to U.S.-Israel relations.

White House spokesman Josh Earnest later backed the comments, but House Speaker John Boehner rejected Rice’s assertion, saying he “couldn’t disagree more” with what she said.
