WASHINGTON - The only Republican still left in President Barack Obama's first-term Cabinet, says he plans to leave the Obama administration.

Transportation Secretary Ray LaHood says in an interview with The Associated Press that he intends to remain at the department until his successor is confirmed.

The former congressman has helped the Obama administration steer through a number of safety measures and highway projects during the past four years. His record has included steps to curb distracted driving, promote high-speed rail projects and improve roads and bridges.

Former Defence Secretary Robert Gates also was a Republican.

LaHood says he will not run for public office in his home state of Illinois, saying he believes "you should go out while they're applauding."
