Earlier this week, U.S. Transportation Secretary Ray LaHood announced to the employees of the U.S. Department of Transportation that after serving for four years in President Obama’s Cabinet, he would not be staying on for the second term. He noted that his plan is to remain in the position until his successor is confirmed.

“Our achievements are significant,” LaHood said in an email to DOT employees. “We have put safety front and center with the Distracted Driving Initiative and a rule to combat pilot fatigue that was decades in the making.”
