WASHINGTON (AP) - Abortion opponents are gathering in Washington for their annual rally and march to mark the anniversary of the Roe v. Wade decision legalizing abortion.
House Speaker John Boehner is scheduled to address the crowd at the "March for Life."
The first march was held in 1974, a year after the landmark Supreme Court ruling. In recent years it has attracted hundreds of thousands of participants.
The rally begins at noon Monday on the National Mall, and participants will then march up Constitution Avenue to the Supreme Court building.
Boehner says in a statement that he's honored to address the march and to lead the House's "bipartisan pro-life majority."
