MSNBC pundit S.E. Cupp, CNN contributor Will Cain and Abby, Liddy and Mary Anne Huntsman, three of former Utah Governor Jon Huntsman's daughters, have joined the group Young Conservatives for the Freedom to Marry.

On Wednesday, the group announced 20 new members to its leadership committee, including Huntsman's daughters.

The new members will be welcomed by current members at a reception to be held on Monday.

Abby Huntsman, host and producer for HuffPo Live, said she was “thrilled to be part of such a diverse, talented group of conservatives who believe in doing the right thing.”

The group also announced that Tyler Deaton, a political consultant and a managing director for b-fresh consulting, will take over as the group's campaign manager.

“The rapid growth of Young Conservatives for the Freedom to Marry reflects the increasing number of Republicans, libertarians, and right-of-center Americans who are completing their own journeys on marriage for same-sex couples,” Deaton said. “When conservatives learn why marriage matters to gay people, they realize that they share the same values as anyone else: Committing themselves to each other, making a lifetime vow of love, and protecting their families. The freedom to marry is not a Democratic or Republican value; it's an American value that we all can and should support.”

Existing members include Meghan McCain and Margaret Hoover.
