A video of Mitt Romney telling a group of conservatives in 2005 that gay parenting is “not right” has surfaced.

The video accompanies a Boston Globe story written by Murray Wass on how Romney, while governor of Massachusetts, actively worked against gay parents, denying them access to new birth certificates.

After the state became the first to legalize gay marriage in 2003, the state Registry of Vital Records and Statistics proposed altering its birth certificate forms to accommodate babies born to gay and lesbian couples. The agency proposed relabeling the box for “father” to read “father or second parent.”

Romney rejected the plan. Instead, he ordered his top legal staff to individually review each request. If approved, officials would then be allowed to make the changes to the form by hand, crossing out the word “father” and substituting “second parent.”

The practice remained in place throughout Romney's term. For lesbian couples, the policy resulted in delays. But gay men were often forced to obtain a court order.

In the video, Romney is seen in 2005 defending the decision to a group of conservative voters in South Carolina.

“Today, same-sex couples are marrying, under the law, in Massachusetts. Some gays are actually having children born to them. We've been asked to change their birth certificates to remove the phrase 'mother' and 'father' and replace it with 'parent A' and 'parent B.' It's not right on paper. It's not right in fact. Every child has the right to have a mother and father,” Romney said. (The video is embedded on this page. Visit our video library for more videos.)

Earlier this year, Romney boasted that he kept Massachusetts from becoming “the Las Vegas of gay marriage,” a reference to the fact that out-of-state gay couples were barred from marrying in the state while Romney was governor.
