Might as well file this under the 2014 midterm elections because I’m betting there is a large political component to this resignation. Holder will stay on until a successor is named which means he’ll still be there for several months at least, likely into 2015.

Report from NPR:

Eric Holder Jr., the nation’s first black U.S. attorney general, is preparing to announce his resignation Thursday after a tumultuous tenure marked by civil rights advances, national security threats, reforms to the criminal justice system and five and a half years of fights with Republicans in Congress.

Two sources familiar with the decision tell NPR that Holder, 63, intends to leave the Justice Department as soon as his successor is confirmed, a process that could run through 2014 and even into next year. A former U.S. government official says Holder has been increasingly “adamant” about his desire to leave soon for fear he otherwise could be locked in to stay for much of the rest of President Obama’s second term.

Holder already is one of the longest serving members of the Obama cabinet and ranks as the fourth longest tenured AG in history. Hundreds of employees waited in lines, stacked three rows deep, for his return in early February 2009 to the Justice Department, where he previously worked as a young corruption prosecutor and as deputy attorney general — the second in command — during the Clinton administration.

As mentioned in the article, Holder’s tenure has not been without controversy, but that statement is fairly true for most Attorneys General who have served this long. Does this do anything for Democratic prospects coming up in November? Holder was controversial to many, but certainly not with the Democratic voting base.
