"House stem cell measure to trigger veto fight."
“The House plans to trigger another veto showdown with President Bush this week by clearing legislation that would expand federally funded embryonic stem cell research.”
Bush has vowed to veto the measure (S 5), just as he did similar legislation last July 19. A veto override attempt in the House that same day fell 51 votes short of the two-thirds majority required.
The Senate passed the stem cell bill by a 63-34 vote April 11. After accounting for absentees that day, Senate supporters of the measure calculate that they are one vote short of being able to override a veto.
