A federal appeals court has rejected an attempt by former President Donald Trump to block his attorney Evan Corcoran from testifying in the investigation led by special counsel Jack Smith. The US DC Circuit Court of Appeals said that Corcoran must provide additional testimony and turn over documents about the former president as part of the criminal investigation into possible mishandling of classified documents. The announcement from the appeals court adds momentum to the special counsel investigation as it seeks to secure evidence that could potentially incriminate the former president.
