The filing deadline for 1st degree amendments to the substitute and underlying bill is 4:00pm today; the 2nd degree amendment filing deadline is set for 12:00pm on Tuesday, September 27th.
As a reminder, during Thursday's session Senator McConnell offered substitute amendment #5082 (text of short-term CR), filled the amendment tree, and filed cloture on the substitute and the underlying bill. The cloture vote on the substitute amendment will be tomorrow, September 27, at 2:15pm. Under the rules, if cloture is invoked there would then be up to 30 hours of debate followed by a vote on the amendment; if cloture is not invoked, the cloture motion on the underlying bill would immediately ripen.
