McDonald's says it’s Twitter account was hacked.

The tweet to Trump from the official account for McDonald’s Corp. has since been deleted but was captured in screenshots.

The message also said it would love to have President Obama back and “also you have tiny hands.”

The tweet was also temporarily pinned to the top of the McDonald’s account so that it would be the top message people see if they visited the company’s Twitter profile.

McDonald’s said in a statement that it took swift action to secure its account, and apologised that the tweet was sent through its corporate account.

The company earlier had said it was notified by Twitter that its account was “compromised.” McDonald’s did not provide any other details.

But the damage was done. The tweet attracted a lot of attention and was retweeted with messages including “It’s McWar” and “They’re not lovin’ it”.

The hashtag #BoycottMcDonalds began trending on Twitter.

The president has not responded to the tweet.

Mr Trump has said in the past that he is a fan of fast food like McDonald’s.

“I’m a very clean person. I like cleanliness, and I think you’re better off going there than maybe someplace that you have no idea where the food’s coming from. It’s a certain standard,” Mr Trump said last year during a CNN town hall.

Mr Trump also appeared in a McDonald’s commercial in 2002 with Grimace in Trump Tower.
