Michael Dell, Richard Branson and Marc Benioff are among the business leaders calling on Georgia Governor Nathan Deal, a Republican, to veto a bill that seeks to protect opponents of marriage equality.

Last week, lawmakers approved House Bill 757 after replacing direct references to same-sex marriages with allowing religious groups to deny services “that violate such faith-based organization's sincerely held religious beliefs.”

Salesforce CEO Benioff has threatened to pull a digital marketing conference scheduled to take place in May if Deal signs the bill into law.

“If HB 757 is not vetoed and instead becomes law, Salesforce will have to reduce investments in Georgia, including moving the Salesforce Connections conference to a state that provides a more welcoming environment for the LGBTQ community,” the company said.

“I'm with @Benioff,” the Huffington Post's Arianna Huffington tweeted, “we need to stand up to discrimination and urge @GovernorDeal to veto anti-gay Georgia House Bill 757.”

Virgin Group founder Richard Branson messaged, “Georgia must stop discriminating in the name of religious freedom,” while Dell CEO Michael Dell tweeted that he was “proud” that Dell SecureWorks had joined a growing coalition of businesses calling on Deal to veto the bill.
