Watch: Same-sex couples rejoice as Colorado governor signs civil unions bill

Colorado's governor on Thursday signed into law a bill that allows same-sex couples in the state to enter into civil unions.

Supporters of the bill packed into the History Colorado Museum to celebrate the signing of SB11, the Colorado Civil Union Act.

"It's about fucking time," one woman said after kissing her partner.

The new law provides committed gay and lesbian couples with many of the legal protections and rights provided to married couples, including adopting children and making end-of-life decisions for a partner.

The development is a dramatic change from 2006, when voters approved an amendment to the state constitution to prohibit same-sex marriage.

Colorado state Reps. Mark Ferrandino and Pat Steadman introduced the first civil unions bill in 2011. The legislation was blocked by Republican lawmakers until this year, when Democrats won back the state House.
