In Wisconsin, it's a crime for a same-sex couple to get married in another state, which the ACLU is also looking to repeal.
"Wisconsin law subjects same-sex couples to an additional harm that is unique among states that deny same-sex couples the freedom to marry," the statement reads. "The only way for Wisconsin couples to get the federal protections that come with marriage is for them to go out of state to marry. But Wisconsin law says that may be a crime punishable by nine months in jail and a $10,000 fine."
The lawsuit in Wisconsin comes as the fight against same-sex marriage ban has been gaining momentum at the state level.
