Trump team won't call witnesses in E. Jean Carroll defamation trial

Former President Donald Trump's legal team will not call any witnesses to the stand in the ongoing trial stemming from author E. Jean Carroll's federal battery and defamation lawsuit, Trump's attorney said Wednesday.

The attorney, Joe Tacopina, told the judge Wednesday that a potential witness, a psychiatrist, will be unable to testify due to a medical issue. Tacopina said Tuesday that the only other person on Trump's witness list, Trump himself, does not intend to testify. 

Defendants are under no obligation to call witnesses at trial and often choose not to, since plaintiffs have the burden of proof to make their case.
