Burger restaurant chain McDonald's has been forced to delete a tweet posted on its official account which appeared to call Donald Trump "a disgusting excuse of a President".
The original tweet read: "@realdonaldtrump You are actually a disgusting excuse of a President and we would love to have @BarackObama back, also you have tiny hands."
In its response, the Illinois-based franchise tweeted: "Twitter notified us that our account was compromised.
"We deleted the tweet, secured our account and are now investigating this."
President Trump has surprisingly not responded to the situation on his own personal account.
But social media users speculated his supporters could call for a boycott of the burger chain.
In January, Starbucks (Hanover: SRB.HA - news) chief executive Howard Schultz pledged to hire 10,000 refugees after Mr Trump signed an executive order banning refugees from several Muslim-majority countries.
Mr Trump's supporters threatened to boycott the coffee franchise in the wake of that declaration.
The US President posed for pictures as he ate fast food on the election campaign last year.
In 2002, he featured in an advert for McDonald's alongside its mascot Grimace.
