Sen. John McCain (R., Ariz.) just gave a barnburner of a speech on the Senate floor. He called for a “spirited debate,” and for Senate majority leader Harry Reid (D., Nev.) to come to the Senate floor and apologize for his recent remarks comparing Republicans to slavery defenders.

After McCain finished, the Senate agreed to spend the rest of the day debating Nelson’s abortion amendment. Turn on C-SPAN 2 now to catch the rest of today’s debate.
