Feb. 17 (UPI) -- Ivanka Trump's elder son was captured making faces Friday in the White House. Joseph Kushner, the 3-year-old son of Ivanka and husband Jared Kushner, was spotted blowing raspberries in the Oval Office. Ivanka later posted a photo on Instagram of Joseph and 5-year-old daughter Arabella peering out of the White House. The 35-year-old businesswoman also shares 10-month-old son Theodore with Kushner. "Watching Marine One land on the South Lawn," she captioned the picture.
