Brownback's campaign questioned Romney's abortion stance Thursday.
WASHINGTON (CNN) - Kansas Sen. Sam Brownback's presidential campaign is adding its two cents to Wednesday's press release battle between GOP presidential rivals John McCain and Mitt Romney over the former Massachusetts governor's abortion stance.
In a statement released Thursday, Brownback's campaign called Romney's "alleged pro-life conversion story" "false and misleading," referencing a YouTube video the McCain campaign posted Wednesday of then-Gov. Romney saying in a 2005 press conference that he was "committed" to maintaining his state's existing abortion rights laws.
Romney has said he started opposing abortion rights in November 2004 after a conversation with a stem-cell researcher made him feel the value of human live had been diminished.
Soon after the McCain campaign circulated the video, Romney's camp fired back, saying “selective editing” had taken the Massachusetts Republican’s comments out of context and called the video's posting “borne of desperation.”
Brownback's campaign questioned Romney's abortion stance last week as well, criticizing him for not directly calling abortion "murder" at a recent campaign event.
