LOOKOUT MOUNTAIN, Tenn. (AP) -- Republican U.S. Sen. Lamar Alexander says he does not support John McCain's push to eliminate gasoline and diesel taxes for the summer driving season.

Alexander made the comment after speaking Monday at the dedication of an addition to the Chickamauga and Chattanooga National Military Park.

Alexander also said he wants to see all money collected from gasoline taxes put into transportation.

Republican presidential candidate McCain has proposed easing high costs at the pump by eliminating the 18.4 cent federal gas tax and 24.4 cent diesel tax from Memorial Day to Labor Day.

By some estimates, the government would lose about $10 billion in revenue.

Alexander says that loss in revenue will hurt road projects and force people to choose which traffic jam to "make worse."
