Washington (CNN) - Rep. Gabrielle Giffords, D-Arizona, had been contemplating a run for Senate before she was shot last month, Democratic sources confirm to CNN.
One Democratic congressman tells CNN he talked to Giffords about it before the shooting, and says she was "very interested in the possibility of running for the Senate."
This congressman, who did not want to speak for the record about private conversations with Giffords, tells CNN that she was considering a Senate run even if Republican Sen. Jon Kyl, R-Arizona, had decided to seek re-election. Kyl announced Thursday he will not run for a 4th Senate term.
"I don't think she [Giffords] ruled out the possibility of running anyway," said the Democratic lawmaker, who said he talked to her about a Senate campaign both in the context of an open seat, or a potential challenge to Kyl.
A second Democratic source familiar with Giffords planning said it was known inside Democratic leadership circles that Giffords was contemplating a Senate run.
"She is an ambitious superstar, and this was definitely on her radar," said the Democratic source.
Gifford's interest in the Senate seat was first reported by the Washington Post.
