Hunter Biden is filing a countersuit against the Delaware computer repairman who triggered the now-infamous laptop controversy.

Biden's lawsuit challenges whether John Paul Mac Isaac followed state law when determining the laptop was abandoned when he copied and distributed Biden's private information.

The suit accuses Isaac of invasion of privacy and conspiracy to obtain and distribute the data.
