Here's the tweet:

The user who Trump retweeted set its location to “Jewmerica.” The user’s bio also links to a documentary that bills itself as "the untold story about the most reviled man in history," Adolf Hitler.

It wouldn't be the first time Trump, or whoever was control of his Twitter account at the moment, retweeted a user who appeared to have white supremacist sympathies. Trump thanked a Dutch white supremacist in October for supporting him.
