Washington (CNN) -- Frustrated Democrats went to the Senate floor Friday to seek Republican approval for a long list of administration nominees currently blocked by controversial secret holds placed by GOP senators. But a Republican senator objected to each of them as they came up. "Most of the people on the list, we don't know why they're sitting there. We don't even know who's making them sit there," complained Sen. Claire McCaskill, D-Missouri, who is spearheading Democratic efforts to banish secret holds. "Enter stage left, the anonymous hold. Or as I like to call it, nobody can blame me cause they don't know who I am."
