Senate committee opens hearings on ATT-T-Mobile merger

How's this for an opening salvo from a politician to this morning's Senate hearings on AT&T's purchase of T-Mobile USA Inc.

According to Wisconsin Democrat Herb Kohl, the combination of the companies has “profound implications” for competition in the telecommunications industry.

Kohl said the combination could mean the phone-carrier market “is in danger of reverting to a duopoly in this century.”

Kohl is chairman of a Judiciary subcommittee on antitrust that is conducting today’s hearing in Washington.Sprint chief executive Dan Hesse is scheduled to testify.

Check back later for Hesse's remarks.

The Star's Washington reporter David Goldstein is on hand for today's hearing.
