On a glide path toward confirmation, Supreme Court nominee Neil Gorsuch declared Wednesday that "when you put on the robe, you open your mind" as he faced a final day of questions from the Senate Judiciary Committee.

Frustrated Democrats, unable to get much out of the Denver-based appeals court judge over 11 hours of questioning a day earlier, suggested they might not vote to confirm him later this month. Regardless, Senate Majority Leader Mitch McConnell has made clear this week that he will see that Gorsuch is confirmed on way or another in the GOP-controlled Senate.

Sen. Dianne Feinstein of California, top Democrat on the Judiciary Committee, gave voice to widespread Democratic complaints Wednesday about Gorsuch, President Donald Trump's pick for the high court.

Gorsuch has said repeatedly that he would adhere to the rule of law and respect the independence of the judiciary, but he has refused to address specifics on any number of issues, from abortion and guns, to allowing cameras in the courtroom, to the treatment of the federal judge nominated last year to the Supreme Court vacancy but denied a hearing by Republicans.

"What worries me is you have been very much able to avoid any specificity like no one I have ever seen before," Feinstein told Gorsuch. "And maybe that's a virtue, I don't know. But for us on this side, knowing where you stand on major questions of the day is really important to a vote 'aye,' and so that's why we pressed and pressed and pressed."
