http://www.nytimes.com/2005/07/29/politics/29stem.html?hp&ex=1122696000&en=6fb840b2ccae5f06&ei=5094&partner=homepageWASHINGTON, July 28 - In a break with President Bush, the Senate Republican leader, Bill Frist, has decided to support a bill to expand federal financing for embryonic stem cell research, a move that could push it closer to passage and force a confrontation with the White House, which is threatening to veto the measure.
Mr. Frist, a heart-lung transplant surgeon who said last month that he did not back expanding financing "at this juncture," is expected to announce his decision Friday morning in a lengthy Senate speech. In it, he says that while he has reservations about altering Mr. Bush's four-year-old policy, which placed strict limits on taxpayer financing for the work, he supports the bill nonetheless.
"While human embryonic stem cell research is still at a very early stage, the limitations put in place in 2001 will, over time, slow our ability to bring potential new treatments for certain diseases," Mr. Frist says, according to a text of the speech provided by his office Thursday evening. "Therefore, I believe the president's policy should be modified."
Mr. Frist's move will undoubtedly change the political landscape in the debate over embryonic stem cell research, one of the thorniest moral issues to come before Congress. The chief House sponsor of the bill, Representative Michael N. Castle, Republican of Delaware, said, "His support is of huge significance."...
...The move could also have implications for Mr. Frist's political future. The senator is widely considered a potential candidate for the presidency in 2008, and supporting an expansion of the policy will put him at odds not only with the White House but also with Christian conservatives, whose support he will need in the race for the Republican nomination. But the decision could also help him win support among centrists.
