The attorney general has not commented on the search at Donald J. Trump’s home in Florida, and the former president and his allies are filling the void with vitriol.
The tax agency said its commissioner asked the Treasury Department’s inspector general for tax administration to look into the audits after The Times raised questions about them.
The former F.B.I. director and his deputy, both of whom former President Donald J. Trump wanted prosecuted, were selected for a rare audit program that the tax agency says is random.
