IRS Commissioner Charles Rettig told a U.S. House subcommittee Tuesday that he’s talked to Treasury Secretary Steven Mnuchin about how to respond to a request by Ways and Means Committee Chairman Richard Neal to turn over six years of President Donald Trump’s tax returns by Wednesday.

Rettig refused to say, however, whether he will ultimately make the decision about releasing those tax records or leave that task to Mnuchin. Neal, who says he has authority to see the president’s personal and business returns under a Tax Code provision, directed his letter to Rettig, formerly a Beverly Hills tax lawyer before he jumped to the Trump administration.
