A spokeswoman for Transportation Secretary Ray LaHood says the former Illinois Republican congressman will leave the Obama administration at the end of the president's current term.
The spokeswoman, Jill Zuckman, said LaHood was asked about his intentions at a media luncheon Thursday. She said he gave no reason for his decision and hadn't discussed his intentions with President Barack Obama.
LaHood was congressman for 14 years until retiring in 2008, and a top aide to former House Minority Leader Bob Michel before that.
