NEW YORK (AP) — The 9/11 Memorial and Museum has launched a $75 million fundraising campaign as the nonprofit tries to educate the millions of U.S. youth who don’t remember the terror attacks on their upcoming 25th anniversary.

Boosting The Never Forget Fund’s latest appeal, announced Wednesday, is Mike Bloomberg. The former New York City mayor, who has rallied hundreds of millions of dollars toward the 9/11 Memorial and Museum as its chair, pledged to match the next $25 million in donations through his Bloomberg Philanthropies. Organizers already secured the first $25 million through unspecified initial gifts.
