Marine Le Pen moves up

• Not so hot on hotlines. When multiple allegations of sexual harassment by Fox News host Bill O'Reilly were reported this month, representatives for 21st Century Fox pointed to the company's anonymous hotline, saying no employee had ever used it to complain about employee behavior.

CNN co-anchor Alisyn Camerota, the most recent Fox News host to come forward with sexual harassment allegations against ex-CEO Roger Ailes, says she did not know of the hotline's existence: "There was no hotline; I can't underscore this enough," she said. "When you have a real hotline, you put up posters: ‘If you see anything, feel anything, here's the number to call.' That did not exist."

The New York Times' Noam Scheiber spoke to a number of employment law experts about such hotlines and found that not only is it typical for employees to be unaware of their existence, but that hotlines often become a tool for suppressing harassment allegations rather than dealing with them. The veneer of anonymity can even make retaliation by the employer easier, he explains: "Companies can claim they could not possibly have retaliated because they did not know the identity of the tipster, when in fact they did."

• Le Pen advances. Far-right populist candidate Marine Le Pen has qualified for France's May 7 runoff election, where she will face centrist Emmanuel Macron.

• The saga continues. Elizabeth Holmes-led blood-testing startup Theranos allegedly misled company directors about its laboratory-testing practices, used a shell company to "secretly" buy commercial-lab equipment, and improperly created rosy financial projections for investors, according to allegations in newly unsealed court filings in a suit by one of its investors. The company disagrees with many of the allegations. Fortune

"As long as that's the case, the biggest financial institutions will continue to put their customers and the economy at risk." New York Times
