Washington DC city council has voted to recognise same-sex marriages conducted in other US states.

华盛顿市议会已经投票承认同性婚姻，对美国其他州起了知道作用。

A number of US states are considering laws to allow same-sex marriage

Because Washington DC is not a state, the decision will now have to be approved by Congress before it can become law.

Four US states - Vermont, Connecticut, Massachusetts and Iowa - now permit gay marriage, and legislation to allow it is in progress in other states.

The resolution was passed in the council by 12 votes to one.

Council member David A Catania - one of two openly gay members of the body - explained his reasons for supporting the measure during the debate.

"This issue is whether or not our colleagues on a personal level view me and [Council member] Jim Graham as your equals," he said.

"If we are permitted the same rights and responsibilities and obligations as our colleagues. So this is personal. This is acknowledging our families as much as we acknowledge you."

Fellow council member, and former Washington DC Mayor Marion Barry, was the only member to vote against the proposal.

"I understand this is personal to you and Mr Graham," he said in response to Mr Catania's remarks.

"I resent（愤恨，憎恶） Mr Catania saying either you are a bigot（盲信者，顽固者） or against bigotry¹ as though this particular legislation represents all of that."

The law will be sent to DC Mayor Adrian Fenty - a supporter of gay marriage - for approval, before being placed before Congress.
