On Thursday, President Obama chose the federal controller of the White House budget office Daniel Werfel to temporarily head the Internal Revenue Service. The appointment will become effective on Wednesday May 22nd, and will put Werfel in the place of Steven Miller, who was pressured to resign as acting commissioner in the midst of a controversy over IRS discrimination against conservative groups.

“As acting commissioner, Mr. Werfel will lead efforts to ensure the IRS implements new safeguards to restore public trust and administers the tax code with fairness and integrity,” the White House said in a statement.

Werfel will serve for the rest of the fiscal year, which ends on September 30th. He has been described as a ‘longtime loyalist’ who may allow the administration to exert a new level of control over the vast agency. Recently, his most central role has been to organize the across-the-board budget cuts known as sequestration.
