The lesbian daughter of former US Vice President Dick Cheney married her longtime partner in Washington DC Friday (22 June).
Mary Cheney and Heather Poe wed on the 20th anniversary of their first date, according to a Facebook post by Cheney who added: 'Very happy to announce that as of this morning, Heather and I are legally married (at least in DC).'
The couple live in Virginia and are the parents of two children, a 5-year-old son named Samuel and a 2-year-old daughter named Sarah.
The former vice president and his wife, Lynne Cheney, said in a statement: 'Mary and Heather have been in a committed relationship for many years, and we are delighted that they were able to take advantage of the opportunity to have that relationship recognized.'
'Mary and Heather and their children are very important and much loved members of our family and we wish them every happiness,' the Cheneys added.
A staunch conservative, Dick Cheney finally endorsed same-sex marriage in 2009. Five years earlier, the Bush-Cheney administration supported the Federal Marriage Amendment, a proposed amendment to the US Constitution that would limit marriage to heterosexual couples and also ban civil unions and domestic partnership benefits.
Cheney did not publicly express her opinion of the amendment at the time but in her 2006 autobiography, she wrote that she was against the amendment.
