Yeah yeah yeah we know how alt-right concern trolls have a hardon when bashing CNN but to do so over a perfectly fine "fun facts" non-political article like this is really scraping the bottom of that already-imaginary barrel.
And this actually isn't even relateable to the mustard thing - that was a clear attempt to attack Obama's character because he didn't eat "American" mustard. Did anywhere in this article even so much as insinuate Trump is "un-American" because he doesn't have a pet in the WH and every other president does? No. That's because liberals actually have class and respect, unlike their counterparts.
