NEW YORK: That is because in 2018, Kaiser had a defining moment: She came forward with information about her former employer Cambridge Analytica, which illegally used Facebook data to persuade undecided U.S. voters to back Donald Trump in the 2016 presidential election as well as to sway British voters to leave the European Union.

In this conversation with Reuters, Kaiser, 38, reflects on the intersection of politics, tech and ethics that shaped her early career.

What was your very first job?
I was an environmental activist working for U.S. Public Interest Research Group, promoting what U.S. Senator Dick Durbin and then-State Senator Barack Obama were doing to stop British Petroleum from dumping into the streams and waterways in Lake Michigan. That was the first time I was paid as an activist, not just volunteering or interning. The first half of my career was mostly nonprofit work.
