Former Treasury Secretary Tim Geithner sat down with Bret Baier today after the release of his new book generated some buzz in the Beltway this week. In “Stress Test: Reflections on Financial Crises,” Geithner tells the story of a meeting with White House advisers Stephanie Cutter and Dan Pfeiffer that occurred before he appeared on Sunday talk shows.

“I objected when Dan Pfeiffer wanted me to say Social Security didn’t contribute to the deficit. It wasn’t a main driver of our future deficits, but it did contribute. Pfeiffer said the line was a ‘dog whistle’ to the left, a phrase I had never heard before,” Geithner wrote.

Critics jumped on the quote, arguing that it's another example of the White House trying to mislead the public, and comparing it to Susan Rice being prepped for Sunday talk shows after the 2012 Benghazi attack.

Geithner, however, disputes the characterization of what he wrote, telling Baier that they were not asking him to mislead. He added that he wouldn't have done so if they did make such a request.

Geithner explained that Pfeiffer was helpfully pointing out that he should not make it seem like Social Security was going to be cut to cover budget shortfalls.

Baier countered that the book "reads differently" than Geithner's explanation of how the conversation went.
