Take a look: Which countries have birthright citizenship?

WASHINGTON D.C. -- There's word of a possible new executive order involving children. In an interview with "Axios on HBO," President Donald Trump says he's considering ending birthright citizenship. The U.S. would not be the first in the world to do so. Right now, 30 countries have birthright citizenship. And all but Fiji are in the Western Hemisphere.

Ireland ended it in 2005 and France in 1993.

Birthright citizenship is a constitutional right. The 14th Amendment states that babies born on U.S. soil are citizens, despite the immigration status of their parents.

The president now says he can end all of that with an executive order.

But the legal groups say the constitution can only be changed through a constitutional convention, ratified by three-fourths of state legislatures, or a two-thirds vote in both houses of Congress. Then, three-fourths of the states affirming the proposed amendment.
