Giuliani said interested in the Senate

NEW YORK, Nov. 20 (UPI) -- Rudy Giuliani, the former New York City mayor rumored to be interested in running for governor, is considering a run for the U.S. Senate, a former aide says.

Giuliani, a Republican, has made no final decision but is "more interested" in the Senate, the source told the Wall Street Journal.

He said Giuliani may seek the New York seat currently held by Democratic Sen. Kirsten Gillibrand, who was appointed to the succeed U.S. Secretary of State Hillary Clinton last winter.

Giuliani's spokeswoman, Maria Comella, denied in a statement that anything had been decided.

"When Mayor Giuliani makes a decision about serving in public office, he will inform New Yorkers on his own," she said.

Giuliani ran for the Senate in 2000 against Democrat Clinton. But, Giuliani withdrew when he learned he had cancer and Clinton went on to win the race.

Giuliani also withdrew from the presidential race in 2008, when it was clear he did not have the support to win the Republican nomination.
