WASHINGTON — Freddie Mac secretly paid a Republican consulting firm $2 million to kill legislation that would have regulated and trimmed the mortgage finance giant and its sister company, Fannie Mae, three years before the government took control to prevent their collapse.

In the cross hairs of the campaign carried out by DCI of Washington were Republican senators and a regulatory overhaul bill sponsored by Sen. Chuck Hagel, R-Neb. DCI's chief executive is Doug Goodyear, whom John McCain's campaign later hired to manage the GOP convention in September.

Freddie Mac's payments to DCI began shortly after the Senate Banking, Housing and Urban Affairs Committee sent Hagel's bill to the then-GOP-run Senate on July 28, 2005. All GOP members of the committee supported it; all Democrats opposed it.

In the midst of DCI's yearlong effort, Hagel and 25 other Republican senators pleaded unsuccessfully with Senate Majority Leader Bill Frist, R-Tenn., to allow a vote.

"If effective regulatory reform legislation ... is not enacted this year, American taxpayers will continue to be exposed to the enormous risk that Fannie Mae and Freddie Mac pose to the housing market, the overall financial system and the economy as a whole," the senators wrote in a letter that proved prescient.

Unknown to the senators, DCI was undermining support for the bill in a campaign targeting 17 Republican senators in 13 states — none from Utah — according to documents obtained by The Associated Press. The states and the senators targeted changed over time but always stayed on the Republican side.

In the end, there was not enough Republican support for Hagel's bill to warrant bringing it up for a vote because Democrats also opposed it and the votes of some would be needed for passage. The measure died at the end of the 109th Congress.

McCain, R-Ariz., was not a target of the DCI campaign. He signed Hagel's letter and three weeks later signed on as a co-sponsor of the bill.

By the time McCain did so, however, DCI's effort had gone on for nine months and was on its way toward killing the bill.

In recent days, McCain has said Freddie Mac and Fannie Mae were "one of the real catalysts, really the match that lit this fire" of the global credit crisis. McCain has accused Democratic presidential candidate Barack Obama of taking advice from former executives of Fannie Mae and Freddie Mac and failing to see that the companies were heading for a meltdown.

McCain's campaign manager, Rick Davis, or his lobbying firm has taken more than $2 million from Fannie Mae and Freddie Mac dating to 2000. In December, Freddie Mac contributed $250,000 to last month's GOP convention.
