Here are the federal requirements for donating blood.
Equality Florida, the state's LGBT rights organization, created a GoFundMe page to raise money for the shooting victims and their families. As of early Sunday night, almost 20,000 donors had raised more than $700,000.
"Funds raised on this page will be going directly to the victims and families affected by the horrific shooting at Orlando's Pulse Nightclub," the fundraising page states. "Equality Florida is working with local organizations -- who are also helping to raise funds -- to ensure the money is distributed properly."
The Gay, Lesbian, Bisexual and Transgender Community Center of Central Florida has also set up a GoFundMe page in an effort to "defray any expenses incurred by the victims and their families."
