RICHMOND, Va. — A Republican supermajority has muscled two of the most restrictive anti-abortion bills in years through the Virginia House, including one that would all but outlaw the procedure in the state by declaring that the rights of persons apply from the moment sperm and egg unite.

The bills passed over bitter yet futile objections from Democrats. And one GOP delegate caused the House to ripple when he said most abortions come as “matters of lifestyle convenience.”
