Parkland student David Hogg rejects Fox News host's apology
A student survivor of a Florida high school shooting has brushed aside a Fox News host's apology after she mocked his university rejections.
Twelve companies have said they are pulling ads from Laura Ingraham's programme after 17-year-old David Hogg tweeted a call for a boycott.
On Wednesday, she accused the activist of whining after he said four colleges had declined his applications.
He has been a target of online abuse since last month's attack in Parkland.
Keeping up the pressure on Friday, David told the New York Daily News: "I would love to see her go."
He tweeted on Thursday night: "I will only accept your apology only if you denounce the way your network has treated my friends and I in this fight.
"It's time to love thy neighbour, not mudsling at children."

The teenage activist - who has amassed nearly 700,000 Twitter followers since last month's attack - told CNN on Thursday: "I think it's great that corporate America is standing with me and the rest of my friends."
He also rejected her invitation to appear on her show and discuss his gun control campaign.
"I think it's really disgusting, the fact that she basically tried promoting her show after apologising to me," he told CNN.
On Friday, the exodus of sponsors continued, despite Ms Ingraham's tweeted apology.
TripAdvisor, JoS A Bank, Expedia, Hulu, Johnson & Johnson, Office Depot, Jenny Craig, Atlantis, Wayfair, Stich Fix, Nestlé and Nutrish have all announced they will withdraw commercials from The Ingraham Angle.
On her Thursday night show, Ms Ingraham ignored the boycott.
Republican campaign strategist Steve Schmidt praised David Hogg as fearless.
"This kid's not scared," he said. "He's not scared of the NRA. He's not intimidated and scared by Laura Ingraham."
The furore touched off on Wednesday when Ms Ingraham posted on Twitter: "David Hogg Rejected By Four Colleges To Which He Applied and whines about it."
The teenager had mentioned to celebrity gossip website TMZ a day earlier that he had been turned away from four colleges in the University of California system.
A day later - as advertisers joined a boycott - the Fox presenter struck a conciliatory tone by praising David's exam grades.
"On reflection, in the spirit of Holy Week, I apologise for any upset or hurt my tweet caused him or any of the brave victims of Parkland," she said.
But a TripAdvisor spokesperson said Ms Ingraham's original comments "cross the line of decency".
Wayfair said "the decision of an adult to personally criticise a high school student who has lost his classmates in an unspeakable tragedy is not consistent with our values".
