The Senate is headed for a second long night as lawmakers battle over Neil Gorsuch's Supreme Court nomination.

There's no sign that one senator is planning to launch another hours-long talk-a-thon, but instead senators from both parties have been taking turns speaking about Gorsuch throughout the day.

Hirono added that she is scheduled to speak from the Senate floor later Wednesday.

The second night of floor speeches comes ahead of a procedural vote on Gorsuch scheduled to occur on Thursday morning.

Trump's nominee will need 60 votes to overcome the initial hurdle, including the support of eight Democrats. If he fails short as expected, Republicans are poised to go "nuclear" and change the Senate's rules.

A final vote on Gorsuch's nomination is expected Friday.
