White House Aide at Soiree Shows Comcast Reach for Deals

At a museum near the U.S. Capitol three weeks ago, 700 guests sampled bratwurst and vodka and watched the Olympics on a mammoth screen. From the second floor, Comcast Corp.’s David Cohen addressed the crowd, which included the Russian ambassador and a White House official.

Four nights later, Cohen donned a tuxedo, bow tie and cummerbund for a White House state dinner. The menu featured Colorado beef, quail eggs and caviar.
