Sen. Tom Coburn has just demanded that the Senate clerk read the single-payer amendment offered by Sen. Bernie Sanders — and it’s 767 pages.

Typically, Senators offering amendments will ask for unanimous consent to avoid reading the entire meausure, but all it takes is one Senator to object to demand its reading, and Coburn objected to Sanders attempt to dispense with the reading of the amendment.

To give you a sense of how this could delay things, it took the Senate clerk 18 minutes to get through the first 6 pages of the amendment, which were the table of contents. At this current pace, it will take 38 hours to get through the entire amendment.

UPDATE: The body of the bill seems to be going faster than the table of contents, but it still looks likely to take at least 12 hours at this pace.
