Huffington Post, 2008 - Obama, Exelon, and their consultant, David Axelrod. A  partnership made in heaven for the nuclear giant Exelon, which has given "at  least $227,000" to Obama's campaign that eventually got them legislation from  the Illinois Senator written with their best interests in mind. . . 
Mr.  Obama scolded Exelon and federal regulators for inaction and introduced a bill  to require all plant owners to notify state and local authorities immediately of  even small leaks. He has boasted of it on the campaign trail, telling a crowd in December that it was "the only  nuclear legislation that I've passed.". . . 
A close look  at the path his legislation took tells a very different story. While he  initially fought to advance his bill, even holding up a presidential nomination  to try to force a hearing on it, Mr. Obama  eventually rewrote it to reflect changes sought by Senate Republicans, Exelon  and nuclear regulators. The new bill removed language mandating prompt reporting  and simply offered guidance to regulators, whom it charged with addressing the  issue of unreported leaks. . . 
Frank M. Clark, executive  vice president to Exelon, and John W. Rogers Jr., a director there, are among  his largest fund-raisers, according to the Times. John W. Rowe, also an Obama  contributor, is chairman of the Nuclear Energy Institute, which is the nuclear  power industry's lobbying group.
