"This is an attempt to find common ground between science and pro-life," Coleman, R-Minn., said in an interview with The Associated Press.
Four years ago, Mr. Bush banned federal funding for embryonic stem cell research on lines not already developed by Aug. 9, 2001. In essence, Coleman is proposing to move that deadline to today.
"He's drawn a line in the sand that's not pro-science," Coleman said of Mr. Bush. "We don't want to be the party that's anti-science. We're not finding real hope" for cures.
Coleman, who opposes legalized abortion, said his proposal would open up hundreds of stem cell lines to research and possible cures for diseases, and would avoid the moral quandary by using embryos that have already been destroyed.
