During the trial of Tifauzia Tyassuma, also known as Doctor Tifa, prosecutors called witness Dian Sandi to testify. She explained how she came to post a scanned copy of President Joko Widodo’s academic diploma on social media. According to her, the posting originated from a series of tweets she created on the X platform under the handle DianSandiU, which traced the president’s educational background. She said the post was intended as an informational thread rather than falsification. The testimony took place at the East Jakarta District Court on 22 October 2026.
