Here's the NYT on Bill Clinton acting on the White House's behalf in the Joe Sestak job offer:
President Obama’s chief of staff used former President Bill Clinton as an intermediary to see if Representative Joe Sestak would drop out of a Senate primary if given a prominent, but unpaid, advisory position, people briefed on the matter said Friday.
Rahm Emanuel, the White House chief of staff, asked Mr. Clinton to explore the possibilities last summer, according to the briefed individuals, who insisted on anonymity to discuss the politically charged situation. Mr. Sestak said no and went on to win last week’s Pennsylvania Democratic primary against Senator Arlen Specter.
The White House did not offer Mr. Sestak a full-time paid position because Mr. Emanuel wanted him to stay in the House rather than risk losing his seat. Among the positions explored by the White House was an appointment to the President’s Intelligence Advisory Board, which provides independent oversight and advice the president. But White House officials discovered it would not work because Mr. Sestak could not serve on the board while still serving in Congress.
. . . The office of Robert F. Bauer, the White House counsel, has concluded that Mr. Emanuel’s proposal did not violate laws prohibiting government employees from promising employment as a reward for political activity because the position being offered was unpaid. The office also found other examples of presidents offering positions to political allies to achieve political aims.
