Bullied bus monitor Karen Klein to meet benefactor Max Sidorov

School bus monitor Karen Klein, the 68-year-old grandmother ruthlessly bullied by middle school students, will meet with the man who started a fundraising campaign that's generated more than $655,000 since video of the attack went viral last week.

Max Sidorov told USA Today he planned to arrive in the Rochester, N.Y., area Tuesday afternoon and visit Klein sometime Tuesday or Wednesday.

"I am looking forward to meeting with her," he said. "It's a great opportunity to finally meet the woman that is changing the world."

Sidorov, a 25-year-old Toronto nutritionist, set up a fundraising page for Klein on Indiegogo.com last Wednesday after watching the now-infamous YouTube video of Klein being harassed and taunted to the verge of tears by the students, the Rochester Democrat & Chronicle reported.

The video has topped 7 million views on YouTube and made Klein a media superstar.

Sidorov originally intended to raise about $5,000 for a vacation for Klein. Donations will be accepted until July 20.

A representative from indiegogo.com said Klein's fundraiser is the fastest- and largest-grossing fundraiser in the website's history. Previously, the website's largest fund raised around $320,000, Reuters reported.

Klein has said she would like to invest some of the funds raised for her, help her children financially and give some of the money to charity, according to USA Today.

A fundraising campaign together to raise money for Sidorov as thanks for his efforts has generated $6,500 in donations as of Tuesday afternoon.
