With the upcoming debate of telecommunication immunity heading for the senate, there has been much speculation on how Obama will approach a meaningful exposure of the  politics involved in the measure.  If Obama does not speak on the floor, his other option would be to use the campaign as a platform.  His opportunity to debate McCain on this issue publicly which would to show his campaign advisers proclivity in  lobbying for the telecommunication industry.

As Newsweek's Mark Hosenball and Michael Isikoff reported in September 2007:

"The nation's biggest telecommunications companies, working closely with the White House, have mounted a secretive lobbying campaign to get Congress to quickly approve a measure wiping out all private lawsuits against them for assisting the U.S. intelligence community's warrantless surveillance programs. ...

"Among the players, these sources said: powerhouse Republican lobbyists Charlie Black and Wayne Berman (who represent AT&T and Verizon, respectively) ... "

What makes that report of interest is the fact that, by the time of Newsweek's reporting on the lobbying activities of Black and Berman, both men were already serving in official capacities in the presidential campaign of John McCain, who has since been fighting the perception that his campaign is unduly influenced by lobbyists.

The Boston Globe described Berman as "a senior McCain adviser" in April 2007, while the New York Times cited Black's role in the campaign in July of that year -- both press mentions coming months before Newsweek's description of an active role for both men in the secret lobbying effort on behalf of the telecom industry.
