It is of the service dog of former US President George HW Bush. Despite the fact that Trump's rise to power included lambasting past presidents, including both Bushes, the President has responded to Bush's death with repeated laudatory comments. Presidents are traditionally asked to eulogize presidents who have died - and in past state events like this, that has been the case - but the Bush family is unlike any other and has another president in the family who will fill that role.
The president's service dog, 2-year-old yellow lab Sully, was with the family as well. For the task of transporting Bush's body on Monday, the plane has been renamed Special Air Mission 41, the number being a reference to Bush's place in the roster of America's presidents.
George H.W. Bush will lie in state at the U.S. Capitol through Wednesday.
Haslam's office announced Monday the Republican will attend the invitation-only funeral service on Wednesday at Washington National Cathedral. Bush will be buried next to his wife Barbara, who died in April, and their daughter Robin, who died of leukemia at the age of three. His death also reduces membership in the ex-presidents' club to four: Carter, Bill Clinton, George W. Bush and Barack Obama. Dozens of foreign leaders and U.S. luminaries are expected.More news: China and USA greenhouse gas levels to new highs
The last funeral for a former president was the one for Gerald Ford, who died on December 26, 2006 and was buried January 2; Ronald Reagan had died two years earlier in June 2004. Bush was eventually rescued by a USA submarine. Sully's own Instagram account describes the dog as "a kinder, gentler labrador", a play on Bush's words in his 1988 acceptance speech, when he called for "a kinder and gentler nation". There, he will help wounded veterans and service members during their recovery.
Bush spokesman Jim McGrath tweeted Monday that Bush will be laid to rest wearing gray socks honoring his days as a naval aviator.
Sully is named after former airline pilot Chesley B.
The casket will then be flown back on the presidential plane to Houston, where the former head of state will lie in repose at St Martin's Episcopal Church - where the Bushes worshiped for decades - until a funeral service at 17:00 GMT on Thursday.
