Stephen King, the prolific Bangor author and frequent Trump critic, found himself on President Donald Trump's social media enemies list on Tuesday after the president blocked King on Twitter.

As you can see above, King was quick to fire back at the move.

As of 2 p.m., King's tweet had been retweeted more than 16,000 times and liked more than 57,000 times.

King followed up the tweet with another, wondering if the "blockage" was some kind of joke.

Others replied to King's tweet, informing him that it was no hoax, as they had been blocked, too. Others shared a recent Boston Globe story detailing the president's actions.

But within a few hours, J.K. Rowling stepped in to help out her fellow author.

Here are just a few of King's most biting tweets regarding Trump.
