Noting that administration officials had moved to replace top executives at Fannie Mae and Freddie Mac, he said, “We’ll do that in the future if necessary.— Asked whether the administration would ensure the enforcement of Congressionally mandated limits on executive pay at companies receiving bailouts, Geithner said, “absolutely.— But Geithner also indicated the administration must do what is “most effective.— A report in the Washington Post said the administration is devising ways for bank executives to get around the limits.White House senior adviser David Axelrod, appearing on “Fox News Sunday,” did not deny the story, indicating that the administration needed these companies to help with the financial system rescue plan. Geithner said any rulemaking on the law would appear in draft form and receive comment before being finalized.Geithner indicated the nation may face double-digit unemployment, but he suggested it could be stopped. “Depends how effective we are,— he said.
