WASHINGTON (AP) - Leading Republicans are joining a push to reconsider the constitutional amendment that grants automatic citizenship to people born in the United States.

Senate Republican leader Mitch McConnell said Tuesday he supports holding hearings on the issue, although he emphasized that Washington's focus should remain on border security.

His comments came as other Republicans in recent days have questioned or challenged birthright citizenship, embracing a cause that until recently was confined to the far right. The senators include Arizona's Jon Kyl, the GOP whip; Alabama's Jeff Sessions, the top Republican on the Judiciary Committee, and Lindsey Graham of South Carolina, a leading negotiator on immigration legislation.
