Today is the cutoff for the Texas legislature's special session. It's also the final day of the session to pass a bill, which was jammed through by the Texas senate's large conservative majority, to severely restrict abortion rights. The bill would restrict all abortions after 20 weeks and place burdens that would effectively shut down most abortion clinics in the state. The senate will pass it by midnight. That is, unless Senator Wendy Davis can stop them with a nonstop, 13-hour filibuster.
