Trump signs executive order aimed at ending birthright citizenship

The big picture: A coalition of civil rights and civil liberties groups filed a lawsuit on Monday night in an effort to halt the executive order.

• The order is also expected to face legal challenges from state attorneys general since it conflicts with decades of Supreme Court precedent and the 14th Amendment — with the AGs of California and New York among those indicating they would do so.

Context: Ratified in 1868, the 14th Amendment was passed to give nearly emancipated and formerly enslaved Black Americans U.S. citizenship.

• "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside," it reads.

Zoom in: Trump signed the order on Monday, just hours after taking office.

Reality check: Thanks to the landmark Wong Kim Ark case, the U.S. has since 1898 recognized that anyone born on United States soil is a citizen.

• The case established the birthright citizenship clause and led to the dramatic demographic transformation of the U.S.

What they're saying: California Attorney General Rob Bonta told Axios the state will immediately challenge the executive order in federal court.

• "[Trump] can't do it," Bonta said. "He can't undermine it with executive authority. That is not how the law works. It's a constitutional right."
• New York Attorney General Letitia James said in an emailed statement the executive order "is nothing but an attempt to sow division and fear, but we are prepared to fight back with the full force of the law to uphold the integrity of our Constitution."
• ACLU said in a Facebook post announcing it would join the groups suing the Trump administration, "An executive order does not have the power to override the Constitution."

Flashback: San Francisco-born Wong Kim Ark returned to the city of his birth in 1895 after visiting family in China but was refused re-entry.

• John Wise, an openly anti-Chinese bigot and the collector of customs in San Francisco who controlled immigration into the port, wanted a test case that would deny U.S. citizenship to ethnic Chinese residents.
• But Wong fought his case all the way to the Supreme Court, which ruled on March 28, 1898, that the 14th Amendment guaranteed U.S. citizenship to Wong and any other person born on U.S. soil.

Zoom out: Birthright citizenship has resulted in major racial and ethnic shifts in the nation's demographic as more immigrants from Latin America and Asia came to the U.S. following the Immigration and Nationality Act of 1965.

• The U.S. was around 85% white in 1965, according to various estimates.
• The nation is expected to be a "majority-minority" by the 2040s.

Yes, but: That demographic change has fueled a decades-old conspiracy theory, once only held by racists, called "white replacement theory."

• "White replacement theory" posits the existence of a plot to change America's racial composition by methodically enacting policies that reduce white Americans' political power.
• The conspiracy theories encompass strains of anti-Semitism as well as racism and anti-immigrant sentiment.

Trump has repeated the theory and said that immigrants today are "poisoning the blood of our country," language echoing the rhetoric of white supremacists and Adolf Hitler.

Of note: Military bases are not considered "U.S. soil" for citizenship purposes, but a child is a U.S. citizen if born abroad and both parents are U.S. citizens.
