NEW YORK (AP) — Former New York City Mayor Rudolph Giuliani is hospitalized in critical but stable condition, his spokesperson said Sunday, days after the Republican hoarsely told his talk show audience that his voice was “a little under the weather.â€

The spokesperson, Ted Goodman, didn't say what sent Giuliani, 81, to the hospital, how long he's been there or what his prognosis is.
