It’s not quite on par with the “birther” movement — a debunked conspiracy theory that suggested U.S. President Barack Obama was not born in America — but Democratic presidential nominee and current U.S. Vice President Kamala Harris reportedly has a semi-secret foreign past, in the form of five years spent in Montreal when she was a teenager.

She doesn’t discuss it much — in fact, her 2019 memoir, The Truths We Hold (subtitled An American Journey), devotes little more than a page to the time spent in Canada. But some recent reporting out the U.S. suggests that those teenage years were in fact formative ones for the future district attorney and politician.
