In a move sure to stir passion among religious conservatives, Obama lifted the restrictions on stem cell funding by the Federal Government. Ex-President Bush issued a compromise order allowing stem cell research on existing lines, but not if new embryos were to be destroyed. He blocked the use of any government money to fund research on human embryonic stem cell lines created after 9 August 2001. He was criticized by both supporters and opponents for that decision. President Obama has removed the funding roadblock for stem cells extracted from recently destroyed embryos. Many religious conservatives believe human life begins at conception.
Here is the video of Obama's announcement.
