Lady to right of POTUS at rally in green tshirt made a show of putting on a black/white plaid dressy jacket. odd choice of jacket to wear over tshirt knowing she would be on tv. There's a few photos of John, Jr. with German Shepherd wearing black/white plaid scarf. same size plaid as jacket. same colors. couldn't embed it. here's link.
