Jeff Merkley holds the Senate floor overnight to make the case against Gorsuch nomination

At 6:45 ET Tuesday evening, Sen. Jeff Merkley (D-OR) headed to the Senate floor to start talking about why he was opposed to the nomination of Neil Gorsuch to the Supreme Court "for as long as I am able." He has enough stamina, and enough material, that he's still going strong more than 13 hours later.
