Billionaire philanthropist MacKenzie Scott donated $45 million to LGBTQ+ youth crisis intervention nonprofit the Trevor Project , the group announced Monday. It's the largest single donation the organization has received, the group said. Scott has now donated hundreds of millions of dollars to various LGBTQ+ nonprofits in the U.S. and around the world over the years. “This historic donation from MacKenzie Scott comes at a time when The Trevor Project has never needed it more," Trevor Project CEO Jaymes Black said in a statement. "LGBTQ+ youth in the U.S. are facing a growing mental health crisis, and the resources they have for support continue to be politicized and jeopardized. This gift provides a safety net for our life-saving suicide prevention and crisis intervention work, offering stability during a period of immense economic and political uncertainty." They added that the money would be strategically invested in order to financially sustain the organization. "Thanks to MacKenzie Scott’s extraordinary generosity, we are well-positioned to continue working toward a world where every LGBTQ+ young person feels safe, seen, and supported exactly as they are,” Black said. Scott had previously donated $6 million in 2020.

A recent study from the organization found that the mental health crisis among LGBTQ+ youth in the U.S. is getting worse, showing increasing rates of anxiety, depression, and suicidality for these young people over time. Last year, the Substance Abuse and Mental Health Services Administration (SAMHSA) terminated the 988 Suicide & Crisis Lifeline’s LGBTQ+ Youth Specialized Services program.
