Iowa on Friday became the 20th state to ban late-term abortions after five months of pregnancy.

The legislation was signed by Republican Gov. Terry Branstad Friday and was cheered by anti-abortion groups. The anti-abortion group Susan B. Anthony's List said it hopes the state action helps prod movement for a similar federal law.

"National Democratic leaders are beginning to turn away from their extreme pro-abortion platform," said president Marjorie Dannenfelser. "As they debate whether pro-lifers should be allowed into the party, pro-life Republicans are unified in their support for common sense pro-life measures."

Dannenfelser was referring to comments from Democratic National Committee Chairman Tom Perez that Democrats who want to be in the party should support abortion rights.

While more states are taking up late-term abortion bans, there hasn't been movement on the federal level to get a federal ban through. The House has approved a federal ban twice, both bills haven't gotten the 60 votes needed to clear the Senate.
