(CBS News) Republican presidential candidate Newt Gingrich said President Obama's comments about having more "flexibility" should be a sign of concern for allies, including Israel. ,/P>
"People have to worry about when a president who has already proven he is a radical says to a Russian president, 'Give me some space so I can get re-elected because then I'll have real flexibility' - you have to wonder," Gingrich said on CBS News' "Face the Nation."
Gingrich told host Bob Schieffer that "you also have to ask yourself how many foreign leaders has he said that to without an open mic. How many other countries are counting on Barack Obama to be, quote, flexible after the election?"
Gingrich is referring to comments the president made last week to outgoing Russian President Dmitry Medvedev that he will have more "flexibility" after the election to deal with the issue of missile defense in Europe.
The former House Speaker also referred to a previous open mic comment when French President Nicolas Sarkozy and President Obama were heard complaining about Israeli Prime Minister Benjamin Netanyahu.
"I would be a little worried and I want to know, what he is going to be like after the election?" Gingrich told Schieffer. "If you look at his policy, he will be more radical."
In a response to a question by Schieffer about whether he would support Romney should he win the nomination, Gingrich said he would "do everything that I can do to elect him."
Gingrich's pledged support comes after he called Romney a liar earlier in the campaign season.
"We are all committed to defeating Barack Obama. We think his re-election would be a disaster for the country," said Gingrich, who remains committed to staying in the race but has obtained only 128 delegates (according to CBS News), compared to Romney's 554.
"I believe he is so radical, and I believe his policies are so dangerous to the United States that I am determined to do everything that I can to help defeat Barack Obama, and there's no question in my mind that Mitt Romney would be a dramatically better president." Gingrich said.
