A spokesman tells The Boston Globe that White House Drug Policy Director Gil Kerlikowske (ker-lih-KOW'-skee) fell ill and fainted Tuesday afternoon while speaking to law students at Harvard University.
Emergency workers treated Kerlikowske at the scene and took him to Massachusetts General Hospital, where he was evaluated and released.
Kerlikowske fainted again at Logan International Airport while on his way back to Washington, D.C., in the evening. He was taken back to the hospital for further evaluation.
Drug office spokesman Rafael Lemaitre says President Barack Obama's chief adviser on drug issues was alert and speaking with doctors.
Kerlikowske is a former Seattle police chief.
