Alan Dershowitz

President Trump vowed to end the blanket right to citizenship for children born on American soil in an interview with Axios Tuesday morning.

But legal eagle Alan Dershowitz, known for his frequent defenses of Trump, says that the 14th Amendment authorizes birthright citizenship and it can’t just be changed by executive order.

“[Birthright citizenship] doesn’t make a lot of sense logically, but it’s in our Constitution and it would be impossible to amend the Constitution to change that, so we’re going to stick with that for better or worse,” Dershowitz told Newsmax in 2015. Dershowitz has yet to comment on Trump’s most recently announced plan to sign an executive order.

The 14 Amendment says: “All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States.”

Seeking to end birthright citizenship would be the most dramatic and probably quixotic move yet in Trump’s hardline immigration policies.

Analysts say he may hope to gin up support in his right-wing base by bringing up the issue, especially as he seeks to change the discussion away from the Pittsburgh synagogue massacre. But it may be controversial even among Trump’s strongest conservative backers who tend to be Constitutional literalists.

A president cannot amend Constitution or laws via executive order. Concept of natural-born citizen in #14thAmendment derives from natural-born subject in Britain. Phrase “and subject to the jurisdiction thereof” excludes mainly foreign diplomats, who are not subject to U.S. laws.— Justin Amash (@justinamash) October 30, 2018
