NEW YORK (CBSNewYork) -- Donald Trump might want to check his old tweets before drinking a Diet Coke in public.
The presumptive Republican presidential nominee posted a photo on Instagram where he's eating McDonald's and drinking a Diet Coke after The Associated Press and CBS News reported that he secured the 1,237 delegates needed for the nomination.
"Celebrating 1237!" Trump posted.
However, Trump tweeted in 2012, "I have never seen a thin person drinking Diet Coke."
Social media pounced on the photo.
Trump should avoid a contested convention in Cleveland.
