The filing deadline for all first-degree amendments to the committee-reported substitute and the underlying bill is 1:00pm tomorrow, Wednesday, March 18.
The cloture vote on the substitute would occur one hour after the Senate convenes on Thursday.
As a reminder, Senator McConnell also entered a motion to reconsider today's failed cloture votes and he could reconsider those at any point. We don't anticipate any roll call votes tonight.
The Senate is now in a period of morning business with senators permitted to speak therein for up to 10 minutes each.
