Republicans invoked the "nuclear option" in the Senate Thursday, unilaterally rewriting the chamber's rules to allow President Donald Trump's nominee to ascend to the Supreme Court.

Furious Democrats objected until the end, but their efforts to block Judge Neil Gorsuch failed as expected. Lawmakers of both parties bemoaned the long-term implications for the Senate, the court and the country.

"We will sadly point to today as a turning point in the history of the Senate and the Supreme Court," said Minority Leader Chuck Schumer of New York.

The maneuvering played out in an atmosphere of tension in the Senate chamber with most senators in their seats, a rare and theatrical occurrence.

First Democrats mounted a filibuster in an effort to block Gorsuch by denying him the 60 votes needed to advance to a final vote. Then Republican Majority Leader Mitch McConnell of Kentucky raised a point of order, suggesting that Supreme Court nominees should not be subjected to a 60-vote threshold but instead a simple majority in the 100-member Senate.

McConnell was overruled, but appealed the ruling. And on that he prevailed on a 52-48 party line vote. The 60-vote filibuster requirement on Supreme Court nominees was effectively gone, and with it the last vestige of bipartisanship on presidential nominees in an increasingly polarized Senate.

A final confirmation vote on Gorsuch is expected Friday and he could then be sworn in in time to take his seat on the court later this month and hear the final cases of the term.

The maneuvering played out with much hand-wringing from all sides about the future of the Senate, as well as unusually bitter accusations and counter-accusations as each side blamed the other. The rules change is known as the "nuclear option" because of its far-reaching implications.
