Six days before Mayor Bloomberg warned both of the state’s U.S. senators that the health care reform bill they were supporting would disproportionately hurt the city, one of the mayor’s closest pals delivered two campaign contributions totalling $4,800 to Sen. Schumer.

Sen. Gillibrand didn’t get a cent.

Records show that the donations from Martin Geller, Bloomberg’s accountant and frequent political alter ego, arrived in Schumer’s account on Dec. 2.

On Dec. 8, Bloomberg and Gov. Paterson told Schumer and Gillibrand in a joint letter that proposed federal health care reforms could cost the state $1 billion and the city hundreds of millions more.

Stu Loeser, the mayor’s spokesman, noted that the contribution to Schumer was “Marty’s money, not the mayor’s.”

That may be so. But it would be a first if Geller were to support someone that the mayor opposed.
