"Right now, I am a firm no, because I do believe that the Senate language on the abortion issue is insufficient for me to support the Senate bill," Rep. Ahn "Joseph" Cao, R-Louisiana, told CNN's Brianna Keilar,
The Louisiana Republican said his concern was that the final legislative package unveiled Thursday by Democrats does not apply to the Hyde Amendment, the longstanding policy against federal funding of abortions, to the federal dollars provided to community health centers.
Cao also said that he thought the language in the Senate bill, which is set for consideration by the House, does not do enough to comply with the Hyde Amendment.
"The present language in the Senate bill provides a tremendous loophole for federal funds of abortion and will eventually expand abortion services," he said.
Cao added, "Based on my reading of the Senate bill, many of the fundings through the health care reform bill will not be subject to the Hyde Amendment."
Asked about the fact that his congressional district is overwhelmingly Democratic and in support of health care reform, the Catholic lawmaker responded, "It is not wrong to vote against what my constituents want but it is wrong to vote against my own conscience."
Cao said if a coalition of House Democrats led by Rep. Bart Stupak, D-Michigan, succeeds in getting stronger language regarding abortion funding into the final legislation, that would "open the door" to him reconsidering his vote.

Last year, when the House passed its own version of health care reform, Cao surprised many political observers by being the only Republican to vote in favor of that bill, a piece of legislation that included provisions regarding abortion demanded by Stupak's coalition.
