"That D.C. grand jury investigation of Abramoff can't go on forever. Eventually the lawyers at the Public Integrity Section will go to their bosses with some decisions about just who they want to indict. That's when Al Gonzales will have to show his cards"

This quote by Joshua Micah Marshall is referring to the grand jury investigation of Jack Abramoff, a lobbyist who was founded guilty of fraud, tax evasion, and conspiracy to bribe public authorities. Marshall is suggesting that the investigation will not last permanently and that the lawyers at the Public Integrity Section will eventually make choices about who to arraign. This is when Attorney General Al Gonzales will have to expose his position on the matter. Marshall is indicating that Gonzales' decision will be an essential consider the outcome of the examination. It is likely that Marshall is recommending that Gonzales' decision will be heavily scrutinized and might have a significant influence on the examination.
