President Obama Overturns Bush Stem Cell Ban
During a ceremony at the White House today, President Obama signed an Executive Order to overturn President Bush’s 2001 restrictions on using federal funds for research on embryonic stem cells. The Executive Order is focused on stem cell research, but it signals a desire by the Obama Administration to return scientific integrity to its policy decisions. Accompanying the Executive Order will also be a Presidential Memorandum to ensure that the government’s scientific decisions are insulated from political influence. This is a welcome change after 8 years of the Bush Administration ignoring or distorting science to further its political agenda.
