I think it was very unprofessional for Russert to say that but, Soc, let's first look at this:
When news organizations reported that Mr. McCain had written letters to government regulators on behalf of the lobbyist’s client, the former campaign associates said, some aides feared for a time that attention would fall on her involvement.
A champion of deregulation, Mr. McCain wrote letters in 1998 and 1999 to the Federal Communications Commission urging it to uphold marketing agreements allowing a television company to control two stations in the same city, a crucial issue for Glencairn Ltd., one of Ms. Iseman’s clients. He introduced a bill to create tax incentives for minority ownership of stations; Ms. Iseman represented several businesses seeking such a program. And he twice tried to advance legislation that would permit a company to control television stations in overlapping markets, an important issue for Paxson.
In late 1999, Ms. Iseman asked Mr. McCain’s staff to send a letter to the commission to help Paxson, now Ion Media Networks, on another matter. Mr. Paxson was impatient for F.C.C. approval of a television deal, and Ms. Iseman acknowledged in an e-mail message to The Times that she had sent to Mr. McCain’s staff information for drafting a letter urging a swift decision.
Mr. McCain complied. He sent two letters to the commission, drawing a rare rebuke for interference from its chairman. In an embarrassing turn for the campaign, news reports invoked the Keating scandal, once again raising questions about intervening for a patron.
Mr. McCain’s aides released all of his letters to the F.C.C. to dispel accusations of favoritism, and aides said the campaign had properly accounted for four trips on the Paxson plane. But the campaign did not report the flight with Ms. Iseman. Mr. McCain’s advisers say he was not required to disclose the flight, but ethics lawyers dispute that.
