Today, the House voted to override President Clinton's veto of a bill banning some late-term abortions. The 285-137 vote was in line with the margin by which the House passed the bill last spring. The Senate vote at that time was well short of the two-thirds margin that would be needed to complete the override. Opponents of the type of abortion described in the bill call the procedure a "partial birth" abortion and say it is immoral. Defenders of the practice say it is sometimes the only procedure available to protect a woman's health. NPR's Brian Naylor reports on today's vote.
