WASHINGTON — Treasury Secretary Steven Mnuchin said Tuesday that his department intends to “follow the law” and is reviewing a request by a top House Democrat to provide President Donald Trump’s tax returns to lawmakers.

But in Capitol Hill appearances on Tuesday, Mnuchin dodged answering whether he would comply with the request to supply Trump’s tax returns by Wednesday, and he also said he has not promised to authorize the IRS to supply the returns.

The head of the IRS, meanwhile, agreed with Democrats that it’s primarily his decision to make — though he reports to Mnuchin. IRS Commissioner Charles Rettig told lawmakers that “we’re working on” a response to a request from Ways and Means Committee Chairman Richard Neal.

“The decision is mine with the supervision of Treasury,” Rettig said.
