The McDonald’s Twitter account created waves in the social media world Thursday morning with a tweet insulting President Trump.

The tweet was published at 6AM and the alleged hacker even pinned it to the account, meaning it appeared at the very top of the account’s Twitter page. McDonald’s has deleted the tweet and claims their Twitter account was compromised.

The company did not take action on the tweet until after 10AM EST. By then, over 1,000 people on Twitter retweeted the tweet and favorited it.

Now McDonald’s will start an investigation:

Trump loves his McDonald’s, too. He ate McDonald’s on his private jet to celebrate his GOP presidential nomination last summer.

He even appeared in a McDonald’s commercial in 2002.
