WASHINGTON (AP) — President Barack Obama picked a senior White House budget official to become the acting head of the Internal Revenue Service on Thursday, the same day another top official announced plans to leave the agency amid the controversy over agents targeting tea party groups.

Obama named longtime civil servant Daniel Werfel as the acting IRS commissioner. Werfel, 42, currently serves as controller of the Office of Management and Budget, making him a key player in implementing recent automatic spending cuts known as the sequester.

"Throughout his career working in both Democratic and Republican administrations, Danny has proven an effective leader who serves with professionalism, integrity and skill," Obama said in a statement. "The American people deserve to have the utmost confidence and trust in their government, and as we work to get to the bottom of what happened and restore confidence in the IRS, Danny has the experience and management ability necessary to lead the agency at this important time."
