Donald Trump’s campaign manager said Tuesday that the businessman and presumptive Republican presidential nominee aggressively took deductions to pay the lowest income-tax rate possible so he could pump the tax savings back into hiring more people for his businesses.

Corey Lewandowski told CBS News that Trump would publicly release his tax returns when the Internal Revenue Service concludes an audit. “Mr. Trump is proud to pay a lower tax rate, the lowest tax rate possible,” he said.
