CIA Blocked IRS From Calling Man Who's Bankrolled Hunter Biden Legal Fees as a Witness, Documents Show

"AUSA Wolf stated that they were provided a classified briefing in relation to Mr. Morris and as a result we could no longer pursue him as a witness," Shapley wrote.

"Investigators probed AUSA Wolf, but since her briefing was classified and she was apparently sanitizing it to an unclassified form to share over an open phone line, she did not elaborate with more information," he continued. "She reiterated more than once that they were summoned to the CIA in Langley concerning Mr. Morris, and that because of the information provided there, he could not be a witness for the investigation."

"It is unclear how the CIA became aware that Mr. Morris was a potential witness in the Hunter Biden investigation and why agents were not told about the meeting in advance or invited to participate. It is a deviation of normal investigative processes for prosecutors to exclude investigators from substantive meetings such as this."

Shapley said he repeatedly requested more information from Wolf but was ultimately unsuccessful.

"Although AUSA Wolf initially appeared to be receptive to facilitating a briefing for me on the information, she ignored multiple attempts by me to arrange the briefing," he said.

"Since obtaining this briefing was outside of my control, eventually I was forced to accept it would not happen. However, it served as yet another example of deviations from normal investigative processes in this matter."
