Ashton Eaton, American Athlete, Shamed Online For Wearing Canada Hat To The Olympics

"Have I not represented USA well?"

RIO DE JANEIRO — Star American decathlete Ashton Eaton says he's represented his country well and has the right to wear a Canadian hat in support of his Saskatchewan-born wife, heptathlete Brianne Theisen-Eaton.

Eaton was seen sporting a red Canada baseball cap at the Olympic track meet on Friday as Theisen-Eaton began her quest for a medal.

The display of Canadian gear did not sit well with some social media users, who suggested he wasn't being a loyal American.

The world champion took to Twitter on Friday night to respond to the criticism.

"Have I not represented USA well? Yet u demand more. Ur respect is hard earned,'' he tweeted. "I support the country that produced my wife;who ru2 shame me?''

Many users also jumped to his defence, applauding him for being a supportive husband.

Theisen-Eaton, who was competing again on Saturday, also responded via Twitter.

"Ashton is my biggest fan & I couldn't do this w/out him,'' she tweeted. "Thank you @AshtonJEaton for always supporting me.''

Athletics Canada also gave him a shout-out.

"Ashton is my biggest fan."

"We appreciate the support for your wife, & we're cool with Bri supporting (the U.S.) when you compete,'' the organization tweeted.

Track and field's super couple are active on social media with the joint Twitter handle @weareeaton. They're also currently starring in a Visa commercial, a tongue-in-cheek depiction of how competitive they are with each other.
