Former US President George Bush Sr has served as an official witness at the same-sex marriage of two long-term friends.
Helen Thorgalsen, who married her partner Bonnie Clement, posted a picture on Facebook of Bush Sr signing some documents with the comment: "Getting our marriage licence witnessed!"
Ms Clement told The Washington Post they have known the former president and his wife Barbara for years and they are "blessed to be in their lives".
The couple were married in Maine, which legalised same-sex marriage in December last year.
George Bush Sr is still recovering in hospital and is likely to remain there for the foreseeable future, his office has said in a statement:
Former President George Bush Sr's condition has improved enough for him to be moved out of the intensive care unit and into a regular patient room at the Houston hospital where he has been receiving treatment, a spokesman has confirmed.
Bush, 88, entered the Methodist Hospital on 23rd November with bronchitis. He was sent to intensive care last Sunday after setbacks including a persistent fever.
"The Bushes thank everyone for their prayers and good wishes," said a statement from the former president's spokesman.
Former US President George Bush Sr remains in intensive care but his condition "continues to improve," his spokesman said.
The chief of staff at the hospital where George Bush Snr is being treated has said that the former US president is likely to remain in hospital for "a while".
"He is 88 years old, he had a terrible case of bronchitis which then triggered a series of complications," Jean Becker wrote in a statement.
"Is he sick? Yes. Does he plan on going anywhere soon? No. He has every intention of staying put.
"He would ask me to tell you to please 'put the harps back in the closet,'" she added.
George Bush Sr has been moved into intensive care after suffering "a series of setbacks that include a persistent fever," according to a family spokesman.
Doctors are "cautiously optimistic" about the 88-year-old former president's health, he added.

The spokesman for the Bush family, Jim McGrath, released this statement on Wednesday:
Former President George HW Bush is in the intensive care unit of a Texas hospital and is in "guarded condition," according to family spokesman Jim McGrath.
"The President is alert and conversing with medical staff, and is surrounded by family," McGrath said in a statement.
Bush was admitted to the intensive care unit on Sunday, he said.
Former US President George HW Bush's fever has worsened with doctors putting him on a liquids-only diet, a spokesman for his hospital in Texas has confirmed.
But Jim McGrath said doctors were "cautiously optimistic" about the course of treatment he is on.
Mr McGrath, who was quoted by the Associated Press, said doctors still do not know what is causing the 88-year-old's "stubborn" fever, despite treating it with Tylenol.
Mr Bush was brought to the Houston hospital for the bronchitis-like cough on November 23.
