The bullying has draw international outrage and an outpouring of support for Karen Klein.
In the video, the children are heard saying:
"Look at all this flab right here."
"Dude put the glasses back on I can't stand to look at your face."
The taunting continued for 10 minutes. The four middle school students in suburban Rochester, N.Y., teased Klein so mercilessly, she cried.
"I tried to ignore them out, that's why I didn't hear some of the stuff because I was trying to shut them out," said Klein.
The father of one of the children in the video is very upset.
"My heart broke. I couldn't believe my son could treat another human being like that," said Robert Helms.
The online posting drew outraged comments. An online fund was started to raise $5,000 to send Klein on a vacation. But so far, it's swelled to $272,000 and counting.
Klein also got a surprise on CNN Thursday when Anderson Cooper told her that Southwest Airlines is going to fly her and nine other people of her choice to Disneyland for three nights, all expenses paid.
The school district is investigating and the four boys will face disciplinary action.
Meanwhile, police in the Rochester suburb of Greece say they've stepped up patrols near the houses of the four students. They have received several threats since the video went viral.
