House Ways and Means Chairman Kevin Brady said he's open toreviewing parts of the House Republican tax blueprint as Congresslooks for a path forward on trying to make U.S. businesses morecompetitive globally — even as Treasury Secretary Steven Mnuchinoffered his most direct criticism of the plan yet.

“We know there are legitimate concerns — including from some ofour witnesses here today and our colleagues on the other side ofthe aisle — about how it will affect American workers, businesses,and consumers,” Brady said Tuesday during a hearing to discuss acontroversial proposal for a border-adjusted tax on imports. “Weare committed to working with all of you to address theseconcerns.”

Meanwhile, Mnuchin sounded a clear warning about the BATproposal during an appearance in Washington.
