More on the Investigation Roberts hel sink....

Investigation into Shelby leak likely to end in the fall:

"The Senate Select Committee on Ethics is expected to end its investigation of alleged classified leaks by Sen. Richard Shelby (R-Ala.) in the next eight to 10 weeks, according to a source familiar with the probe.

The pace has been slowed by difficulties obtaining information, difficulties created partly by Sen. Pat Roberts's (R-Kan.) decision not to recuse himself from the case, the source said. The investigation has been conducted 'off and on' for six months.

Two potential witnesses told The Hill earlier this year that they would be reluctant to cooperate with the Ethics Committee unless Roberts recused himself because he is chairman of the Senate Select Committee on Intelligence and inherited senior aides from Shelby, the previous chairman.

The conclusion of the probe could have political consequences for Shelby, who won reelection last year; possible penalties include censure and expulsion from the Senate."
