Democratic leaders in Congress asked the Bush administration on Saturday to provide more aid to the struggling auto industry, which is bleeding cash and jobs as sales have dropped to their lowest level in a quarter-century. House Speaker Nancy Pelosi and Senate Majority Leader Harry Reid said in a letter to Treasury Secretary Henry Paulson that the administration should consider expanding the $700 billion bailout to include car companies. “A healthy automobile manufacturing sector is essential to the restoration of financial market stability, the overall health of our economy, and the livelihood of the automobile sector's work force,” they wrote. “The economic downturn and the crisis in our financial markets further imperiled our domestic automobile industry and its work force.” Automakers already want an additional $50 billion in loans from Congress to help them survive tough economic conditions and pay for health care obligations for retirees. The companies are seeking the loans as part of an economic aid plan that is now more likely to come together early next year.
