President Obama's campaign said he was "disappointed" that North Carolina voters approved a constitutional amendment banning gay marriage in the state.
"The president has long opposed divisive and discriminatory efforts to deny rights and benefits to same-sex couples," Obama North Carolina campaign spokesman Cameron French said, in a Tuesday statement on the vote over Amendment 1.
Those comments come as the administration faces increasing pressure from pro-gay rights supporters to fully embrace same-sex marriage.
Obama, who supports civil unions but has not publicly endorsed gay marriage, has described his own views on the matter as "evolving," but senior members of his administration have staked positions beyond the president.

This week, the head of the Democratic Caucus said that a majority of House Democrats supported Biden's view, increasing pressure on Obama.
Voters in the North Carolina referendum approved the gay-marriage ban overwhelmingly, by 61 to 39 percent.
The state amendment had attracted national attention with former President Clinton recording robocalls encouraging voters to reject the measure, saying it would "hurt families and drive away jobs."
