WASHINGTON — The Treasury Department announced the appointment of four new senior staff members late Friday, as Treasury Secretary Steven Mnuchin gets ready to lead the administration’s efforts on tax and financial reform.
Joining Treasury as counselors are Dan Kowalski, Shannon McGahn, Justin Muzinich and Craig Phillips. The positions do not require Senate approval.

"I am pleased to have these highly capable and accomplished individuals join my Treasury leadership team," Mnuchin said. "I look forward to having their valuable input and leadership as we move President Trump's ambitious economic growth agenda forward on behalf of the American public."
Kowalski most recently was deputy staff director of the Senate Budget Committee. He will be focused on the federal budget and infrastructure issues and worked for the Trump campaign on similar policy issues.
McGahn, formerly staff director for the House Financial Services Committee under Chairman Rep. Jeb Hensarling, R-Tex., will lead the public and legislative affairs efforts for Treasury and Muzinch will work on tax reform. Muzinich was previously president of Muzinich & Co., an international investment firm, and taught at Columbia Business School.
Phillips, formerly of BlackRock, will help Mnuchin on domestic finance, housing finance policy and regulatory reform.
