Gingrich also questioned the veracity of the jobs report, pointing to comments Friday by former General Electric CEO Jack Welch, implying the stronger-than-expected jobs report may have been politically motivated to boost Obama's re-election prospects, though he conceded he had no proof.
"So you have a president of the United States so deeply distrusted by people like Jack Welch who's hardly a right winger. ... Welch instantaneously assumes this is the Chicago [corruption] issue. I'm just -- it's worth looking at it," Gingrich said.
