Fox has devoted more than 12½ hours of airtime to Weinstein since Oct. 5, when The New York Times broke the story about his misconduct, according to the liberal media watchdog Media Matters for America.

By contrast, Fox has spent 20 minutes, 46 seconds, on the accusations against O’Reilly since the Times revealed many of them in April, the group said.

A news organization’s instinct to downplay a story that reflects poorly on itself isn’t unusual. But in this case, some are attributing the disparity to politics. Weinstein has long been a supporter of liberal causes, while O’Reilly is a hero to many on the right, for whom Fox is the network of choice.
