Washington, D.C. ? President Barack Obama plans to announce today a former Secret Service agent who helped expose lobbyists’ corruption at the Interior Department as his pick to oversee the $787 billion economic stimulus plan.

Obama is set to name Earl Devaney as chairman of the new Recovery Act Transparency and Accountability Board, an administration official said Sunday. Vice President Joe Biden also will be given a role coordinating oversight of stimulus spending.

The official spoke on the condition of anonymity because the White House had not made public the announcement.

Devaney, the inspector general of the Interior Department, helped turn up disgraced lobbyist Jack Abramoff’s dealings at the department.
