The transcript was published by the House Judiciary Committee on New Year’s Eve.
It details Smith’s defence of two criminal investigations.
The probes examined classified documents and attempts to overturn the 2020 election.
Trump pleaded not guilty and the cases later ended after re election.
Video of nearly eight hours of closed door deposition testimony was released.

The deposition took place on 17 December.
Smith was appointed by attorney general Merrick Garland.
He wrote a report supporting charges before leaving office.
