NEW YORK (AP) — Fox News Channel host Laura Ingraham is expected back at work on Monday following a backlash by advertisers upset over her tweet mocking a Parkland, Florida, school shooting survivor. Her one-week vacation served as a cooling-off period. The number of companies saying they would not advertise on her show, at 19, according to a count by Media Matters for America, slowed to a trickle while she was away.
