The Star of David imagery used in a Twitter post by Donald J. Trump this weekend had previously appeared on a message board known for anti-Semitism and white supremacy, as well as on a Twitter account with a history of racially charged comments, according to a report.

It is unclear where the Trump campaign discovered the image, which placed the shape of the Star of David beside a picture of Hillary Clinton with text that read, “Most Corrupt Candidate Ever!” and a background of $100 bills. The post on Saturday by Mr. Trump prompted immediate criticism, fueling accusations that Mr. Trump was playing to stereotypes of Jews.

Later on Saturday, Mr. Trump deleted the post and added another image with a circle covering the star, though tips of the star were still visible. While Mr. Trump’s campaign has been silent on the episode, and did not respond to requests for comment, some of his defenders have argued that a six-pointed star is a symbol used by many sheriff’s departments.

But a report on Sunday by the news website Mic traced the image to a website for the “alt right,” an internet-based movement associated with white nationalism, where it appeared as early as June 22. The origin of the image appeared to be a Twitter account that has frequently criticized Mrs. Clinton, the presumptive Democratic presidential nominee, and has posted caustic and violent messages about Muslims, refugees and race.
