Sen. Lindsey Graham, R-S.C., said on Sunday that "there's a good chance" the U.S. Supreme Court will side with President Trump on birthright citizenship.

Trump signed an executive order to eliminate birthright citizenship. A federal judge blocked it from taking effect.

"I think there's a good chance. I introduced legislation to end birthright citizenship years ago. Canada, Mexico, and the United States are, like, three of the 20 economic powers in the country. There are three of us that do this. Maybe Brazil," Graham said on "Meet the Press."

Graham said the children of illegal immigrants receiving automatic U.S. citizenship if they are born in the U.S. encourages more illegal immigration.

"So, it's a magnet for illegal immigration," he said.

"I think when it comes to illegal immigration, if you want to turn off the spigot, change this policy. I think it's a cheap way to award citizenship. You should not be a citizen simply because you were born here. You have to have some connection to the jurisdiction of the United States," he added.

Graham referenced a new report that showed there were as many as 250,000 people born in the U.S. to illegal immigrants in 2023. 

"That's 7% of all the babies born in the country," he said.
