"I am not taking part in the negotiations (with the Palestinian Authority), but if Obama's sole request from Israel is that it freeze (settlement construction), (Prime Minister Benjamin) Netanyahu's answer should be yes," the Kadima chairwoman said.
"For me, a moratorium has nothing to do with ideology. What are a few buildings compared with the people's desire for peace?" she told "Meet the Press".
Livni said she told the PM he must make every effort to prevent the peace talks from collapsing.
As for Defense Minister Ehud Barak, the head of the Labor Party, she said, "He is working against the policies of the government he is a part of."
Addressing the possibility that former IDF chief of Staff Dan Halutz would join Kadima, Livni said, "We need worthy people in politics, and he is worthy in my eyes."
She said Halutz has yet to reach a final decision on the matter.
