How can the Democrats delay the confirmation process? I would think that the Judiciary Chairman, Grassley, controls the timing of the confirmation process.
Trump just got another Assistant AG confirmed but even with that one done still IIRC more than half of the Assistant AG slots are not yet Trump appointees. Here a year and a half later.
The Democrats in the Senate will require to see all of Kavanaugh’s papers while he served in government. Normally Main Justice lawyers (in other words, Obama holdovers) will process those for things like executive privilege, national security information and so forth.
Sessions is bringing in more troops from the field back to HQ in order to get the documents out more quickly and not let lawyers in Main Justice drag their feet on document processing which might jeopardize getting Kavanaugh confirmed before the Supreme Court term starts in October.
