The Colorado state House has signed off on a bill legalizing civil unions for gay couples, and the bill is expected to be signed Gov. John Hickenlooper (D).

The state House voted 39 to 26 in favor of the bill, which the state Senate had already passed.

Colorado would become the sixth state to legalize same-sex unions but not gay marriage, according to the National Conference of State Legislatures. Ten other states have legalized gay marriage. (The Minnesota state legislature this week is considering legislation that would make it the 11th to approve gay marriage.)
