Trump attorney faces questioning in documents probe, as evidence mounts against him.

Special counsel investigators are expected to question Trump lawyer Evan Corcoran in testimony that could prove key to their decision on whether to charge former President Donald Trump with mishandling classified documents after leaving the White House and obstructing the government's efforts to retrieve them. Corcoran was expected to testify as soon as Friday, after an appeals court ruled Wednesday that Corcoran must testify in the special counsel's probe into Trump's handling of classified materials after leaving the White House.
