Buoyed by conservative gains in the November election, foes of abortion are mobilizing on behalf of bills in Congress and several states that would further curtail women's access to the procedure.
On both sides of the debate, activists are highlighting their hopes and concerns in conjunction with Thursday's anniversary of the Supreme Court's 1973 Roe v. Wade decision that legalized abortion nationwide.
Coinciding with the annual March for Life in Washington, the Republican-controlled House of Representatives plans a debate Thursday on a bill that would ban most abortions after 20 weeks of pregnancy. The bill is expected to pass in the House, but its prospects in the Senate are uncertain, and President Barack Obama has promised a veto.
Several proposed bills at the state level may have better prospects.
