For one, it clearly states that American citizenship is a birthright for all people who are born on American soil -- something that President Donald Trump has announced he wants to end
. Not only would this unravel 150 years of American law, it would loosen a significant cornerstone of the Constitution's interpretation of American identity.
In order to better understand this part of the 14th Amendment, we asked two experts in constitutional and immigration law to walk us through the first section. The amendment has five sections, but we will only be dealing with the first, which contains the Citizenship Clause and three other related clauses.
But first, some history
The 14th Amendment is known as a Reconstruction amendment, because it was added to the Constitution after the Civil War in 1868. That places it at an important historical crossroads, when lingering wounds of divisiveness and animosity still plagued the nation and the reality of a post-slavery America begged contentious racial and social questions.
"Thomas Jefferson said men were created equal, but the original Constitution betrayed that promise by allowing for slavery," says Jeffrey Rosen. "The 13th, 14th and 15th amendments were designed to enshrine Lincoln's promise of a new America."
However, as so often is the case, this reaffirmed American ideal fell short of reality. Rosen notes that issues of civil rights and equal treatment continued to be denied to African Americans, LGBT people and other citizens for more than a century after the amendment's ratification.
And Erika Lee points out that Native Americans weren't even allowed to become citizens until 1925.
"Even as [these amendments] were written, obviously there were major built-in inequalities and maybe at the time weren't intended to apply to everyone," Lee says.
