The U.S. House of Representatives reapproved a bill on Thursday to expand federal spending for research on human embryonic stem cells, but not by a large enough margin to overturn an expected veto by President Bush.
The president vetoed an identical measure last year and vowed this week to do so again. But Democratic leaders viewed Thursday’s move as a way to ratchet up pressure on Mr. Bush to reverse himself, or at least compromise, to accelerate a form of research that many Americans and universities support.
