Former Gov. George Pataki, after a two-month break, announced Wednesday that he is joining a New York City law firm and will specialize in environmental issues, particularly renewable energy. Pataki, who has been eyeing a possible run for the 2008 Republican presidential nomination, will be joined at Chadbourne & Parke by his former chief of staff, John Cahill.

Pataki spokesman David Catalfamo said the governor is not ruling out a possible later jump into the presidential campaign, although Pataki has lately cut back on campaign-like activities.

"I am thrilled to be joining Chadbourne," said Pataki in a news release issued by the law firm. "This is one of the great New York firms, and I look forward to participating in its growth."

Chadbourne's managing partner, Charles O'Neill, said the addition of Pataki and Cahill to the firm "will build upon Chadbourne's growing renewable energy practice."

Cahill is a former state environmental conservation commissioner. Pataki was praised by environmental groups throughout his 12 years in office, particularly for his efforts to add 1 million acres of preserve land to the state.

Pataki, who ousted Democratic Gov. Mario Cuomo in 1994, did not seek re-election last year to a fourth, four-year term.
