Obama’s nominee to lead Social Security agency could be left dangling

Even as the Senate plows through votes on nearly two-dozen Obama nominees, at least one controversial pick could be left dangling amid objections from Republicans over an ongoing investigation into a troubled computer project.

Over the weekend, Senate Democrats canceled a procedural vote on Carolyn Colvin's nomination to lead the Social Security Administration. The move could easily push off consideration of Colvin until next year -- when Republicans control the Senate.

The delay comes after Republicans urged the Senate to wait until the investigation at her agency is resolved.

"It may very well turn out that Ms. Colvin did nothing wrong -- but we need to know for sure," Sen. Orrin Hatch, R-Utah, said last week.
