WASHINGTON (AP) – A watchdog has found that the Treasury Department appropriately handled Congress’ request for President Donald Trump’s tax returns, which Treasury Secretary Steven Mnuchin has refused to provide. But the acting inspector general for Treasury, Rich Delmar, also said he had no opinion on whether the advice Mnuchin followed – which came from Justice Department attorneys – was itself well-founded. Delmar noted in a letter Wednesday to senior House lawmakers that in refusing to hand over the returns, Mnuchin decided he was legally bound to comply with that advice.
