Debate was under way Wednesday in Argentina's Senate on a same-sex marriage bill that already has passed the lower chamber of Congress. A vote was expected later Wednesday.
The bill would give same-sex couples equal marriage rights, including the ability to adopt children.
Addressing claims that church leaders have been lobbying lawmakers about the proposal, Sen. Miguel Angel Pichetto told the state-run Telam news agency that he had not been pressured.
"There is some pressure in some provinces where the church plays a prominent role, but such is democracy," he said.
