It did not work last year, so Democrats are trying again.
On Thursday, Congress sent President Bush another bill to fund embryonic stem cell research.
Does this bill have any chance of becoming law?
With six fewer House votes than they had in January, Democrats sent President Bush a bill allowing the government to pay for embryonic stem cell research.
For some lawmakers, like Rep. Ed Perlmutter of Colorado, it is personal: “This can help my daughter have no more seizures. It's a potential, a possibility.”
For others, like Rep. Mike Pence of Indiana, it is economic: “They want pro-life Americans, like me, to get our wallets out and finance it, and I'm not having that.”
Whatever the reason, lawmakers have strong emotions about research some say will save lives and others argue destroy them.
Rep. Joe Pitts of Pennsylvania said, “Just this morning, more news of progress using ethical stem cell research.”
Scientists say they have turned regular skin cells in mice into embryonic ones.
“They looked exactly the same. We never found any difference,” said Kathryn Plath, a researcher from UCLA.
If replicated in humans, this finding could one day make the whole ethics debate irrelevant.
Until that happens, many people with debilitating diseases insist that embryonic stem cells are their best hope.
Even with the promise of a second presidential veto, supporters are not giving up.
In a statement from Germany, President Bush called the vote disappointing.
The new democratic leadership has made stem cell research one of their top priorities.
President Bush has made it clear he will not budge, which means this issue may be at a standstill until after the 2008 elections.
President Bush has already promised to veto the bill.
On Thursday, the house was 35 votes short of the margin they would need to override it.
Public opinion polls show widespread support for stem cell research.
We want to know what you think.
Was Congress right to approve legislation supporting embryonic stem cell research or do you agree with President Bush?
