San Francisco-based Salesforce on Thursday threatened to pull a digital marketing conference out of Georgia if Governor Nathan Deal does not veto a bill that seeks to protect opponents of marriage equality.

Lawmakers approved House Bill 757 on Wednesday 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.”

Chad Griffin, president of the Human Rights Campaign (HRC), said that the changes “make an egregious and discriminatory bill even worse” and called on Governor Deal, a Republican, to veto the proposal.

Salesforce Connections is scheduled to take place in Atlanta in May.

“The legislation creates an environment of discrimination and makes the state of Georgia seem unwelcoming to same-sex couples and the LGBTQ community,” the company said in a statement. “We were encouraged by Governor Deal's recent comments that he would veto any bill that allows the perception of discrimination and we are now calling on him to stand by his comments and move quickly to veto HB 757. 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.”

Last week, Deal broke his silence on the bill and called for a compromise that would protect religious beliefs without discriminating.
