Story highlights Super PAC officials on Thursday filed documents with the FEC for a new group, Rebuilding America Now

About four donors account for the $32 million, Barrack told CNN

Washington (CNN) A close associate of Donald Trump, Tom Barrack, told CNN's Erin Burnett on Thursday that a new pro-Trump super PAC has secured $32 million in financial commitments. The move could potentially upend Trump's existing super PAC structure.

Super PAC officials earlier in the day filed documents with the FEC for a new group, Rebuilding America Now, that Barrack said had attracted tens of millions of dollars in early money. Barrack, who hosted Trump's first major fundraiser, has long been pointed to by donors as an eventual point man for Trump's super PAC operation, which thus far is nascent and has yet to attract large donations. He said he will not have a formal role with the group.

About four donors account for the $32 million, Barrack told CNN. These include new donors who have never donated large amounts of money to the Republican Party before. It took five phone calls to woo the donors, Barrack said, who he declined to identify.

Barrack said the principal operatives behind the group are Ken McKay and Laurie Gay. McKay, the former campaign manager to New Jersey Gov. Chris Christie, is currently a senior adviser to Trump's campaign and would be required by election law to "cool off" from the campaign before aiding an outside group.

Gay is an ally of Paul Manafort, Trump's chief strategist and one power center in Trump's cadre of aides. The treasurer for the group is Ryan Call, a former chair of the Colorado Republican Party.
