The chairman of the House Oversight and Government Reform Committee said Friday that President Obama used the bailout of U.S. auto companies to “strong-arm” them into agreeing with high gas-mileage standards.

Rep. Darrell Issa (R-Calif.) said the standards, which call for cars to get 54.5 miles per gallon by 2025, were negotiated when the U.S. auto industry was financially dependent on the federal government.

“In the wake of a massive taxpayer funded bailout of General Motors and Chrysler, the Obama administration took aggressive action to force a rulemaking process that reflects ideology over science and politics over process and law,” Issa said of the report in a statement released by his office.
