This time it's WSJ's Elizabeth Williamson who called the President out. From Friday's pool report:
Sasha came first in white top and brown shorts followed closely by flotus in grey sleeveless top and white cropped pants. After a short break came potus in white shirt and his grey jeans looked to your pooler rather mom-like. He was smiling and laughing, said "hi guys" to pool. Next was Malia, also laughing, in blue sleeveless top and shorts. All four in the family wore helmets, unlike last year when potus did not wear a helmet.
