Trump took to Truth Social to criticize a potential witness, former Georgia Lt. Gov. Geoff Duncan, who was scheduled to testify before a special grand jury investigating Trump's election interference in Georgia. Legal experts said this amounted to witness tampering. Trump then attacked the judge overseeing his Washington D.C. election conspiracy case for being biased against him. He had previously made unfounded claims that the Georgia district attorney investigating him, Fani Willis, had an affair with a gang member. Willis denied the allegations as false and derogatory. If another defendant engaged in similar behavior on social media about a witness, they could face witness tampering charges or be jailed. The judge in Trump's D.C. case had recently warned him to stop making antagonizing statements, but he continued his attacks on Truth Social.
