DENVER — Same-sex couples are at the Colorado Capitol to testify for a bill that would grant them similar rights to married couples.

The proposal is one of the most anticipated this session and likely to be among the most emotionally charged. Similar legislation failed last year in the Republican-controlled House after easily passing the Democratic-led Senate with bipartisan support.

The bill would grant same-sex couples rights similar to those of married couples, including the ability to be involved in their partner's medical decisions. It also would enhance inheritance and parental rights.
