Unless an agreement can be reached, the cloture vote would occur one hour after the Senate convenes on the second legislative day. That vote could occur as early as 1:00am on Friday, June 12.
The filing deadline for second degree amendments to the McCain for Burr amendment #1569, as modified, (cyber-security) to McCain #1463 (substitute) to H.R.1735, NDAA, is one hour prior to the cloture vote.
