President Trump's conspiracy theory about Kamala Harris

President Trump said he had "heard" that Kamala Harris - a US-born citizen whose parents were immigrants - "doesn't qualify" to serve as US vice-president. He also shared the opinion piece published in Newsweek magazine by John Eastman, a law professor at Chapman University in California, that Mr Trump was asked about. Prof Eastman cites Article II of the US Constitution's wording that "no person except a natural born citizen… shall be eligible to the office of president". Prof Eastman's argument, which he claims is also being made by other "commentators", hinges on the idea that Ms Harris may not have been subject to US jurisdiction if her parents were, for example, on student visas at the time of their daughter's birth in California. "Her father was (and is) a Jamaican national, her mother was from India, and neither was a naturalized US citizen at the time of Harris' birth in 1964. That, according to these commentators, makes her not a 'natural born citizen' - and therefore ineligible for the office of the president and, hence, ineligible for the office of the vice president," he wrote in the Newsweek op-ed.

Berkeley Law School Dean Erwin Chemerinsky told CBS News that Prof Eastman's argument about Ms Harris' eligibility was "truly silly". "Under section 1 of the 14th Amendment, anyone born in the United States is a United States citizen. The Supreme Court has held this since the 1890s. Kamala Harris was born in the United States," he said.
