Michelle Obama has announced a £128m ($200m) partnership between the US and the UK to help educate adolescent girls in developing countries.
Writing in the Financial Times, the First Lady said girls face obstacles to education such as forced marriages, early pregnancies, abuse and sexism, and described this as "a heartbreaking injustice".
She said the UK was a "global leader" for girls' education, and announced that "British and American partners will work together to support teacher training, girls' leadership camps, and other community-based programmes in developing countries".
She is meeting David Cameron later today to discuss the matter.
The Democratic presidential candidate may also have shown his cards on his choice of running mate.
The US president also shared a post on Twitter accusing Dr Anthony Fauci of misleading the public over hydroxychloroquine.
