Jodie Beggs, a Boston based ‘behavioral economist’, mocked the 11-year-old on Twitter, writing on Monday: ‘Barron Trump is wearing a shirt that reads “The Expert” and I just threw up in my mouth a little.’ She was referring to the $29.50 J. Crew grey and blue garment that Barron was pictured wearing as he arrived at The White House with his parents on Sunday. Beggs, who claims to have worked for Northeastern University, was savaged by Trump fans and impartial Twitter followers who condemned her for picking on a child. She offered no remorse and later, while trying to defend them, said the child’s shirt ‘made him look like a jerk’. The schoolboy, the youngest of President Trump’s five children, has just relocated with his mother from their home in Manhattan to Washington DC.
