Exclusive: Blackmun to be new U.S. Olympic Committee boss [Updated]

Scott Blackmun will be the new chief executive of the U.S. Olympic Committee, sources told the Tribune today.

The USOC board has chosen him over Chuck Wielgus, the CEO of USA Swimming.

USOC chairman Larry Probst is to introduce Blackmun, 52, to the staff Wednesday in Colorado Springs, Colo.

Many of the staff already know him, since Blackmun, an attorney, served the USOC in a variety of positions from 1999 to 2002. He was acting CEO from Nov., 2000, through Oct., 2001.

[Updated at 10:21 a.m.: An earlier version of this post incorrectly stated the dates that Blackmun was acting CEO.]
