WASHINGTON — On the Senate floor and the television airwaves, Senator Mitch McConnell has lambasted the Obama administration over what he has described as its failed efforts to stimulate new jobs through clean-energy projects backed with billions of dollars in federal loans or other assistance.

But Mr. McConnell, of Kentucky, is one of several prominent Republicans who have worked to steer federal money to clean-energy projects in their home states, Energy Department documents show.

Mr. McConnell made two personal appeals in 2009, asking Energy Secretary Steven Chu to approve as much as $235 million in federal loans for a plant to build electric vehicles in Franklin, Ky.

“I hope you will realize the importance of such job creation to Kentucky,” Mr. McConnell said in a July 2009 memo supporting an application from Zap Motor Manufacturing.
