Karen Pence, the Second Lady of the United States, will attend the Special Olympics World Games in Abu Dhabi next month.
Writing on Twitter, Ms Pence, the wife of Vice President Mike Pence, said she was “honoured to represent the United States and lead the Presidential Delegation” for the World Games.
"Looking forward to a wonderful event and cheering on all the amazing athletes with intellectual and developmental disabilities. Go @specialolyUSA" she wrote.
Ms Pence, who also led the Presidential Delegation to the Special Olympics World Winter Games in Austria in 2017, worked as a teacher for 25 years until she became the First Lady of Indiana in 2013.
She works with a number of charities, and has a particular interest in art therapy.
