Klein Will Become Antitrust Chief

Joel I. Klein, now the No. 2 official in the Justice Department’s antitrust division, will become the acting chief when Anne K. Bingaman returns to the private sector this fall.

Klein, 49, has been principal deputy assistant attorney general in the division since April 1, 1995. Before that, he was a deputy White House counsel from 1993.

Bingaman announced Aug. 1 that she would step down as assistant attorney general no later than Nov. 15.
