Claire McCaskill announced on Friday that she will not support the nomination of conservative Judge Neil Gorsuch to the Supreme Court and will join a Democratic effort to block his confirmation vote, which is scheduled for next week.
"I can not support Judge Gorsuch because a study of his opinions reveal a rigid ideology that always puts the little guy under the boot of corporations", McCaskill said. "And anybody who wants to launch partisan attacks for her standing against a judge who's used his courtroom to let the rich and powerful step all over working people, should have to answer for why they're refusing to stand with working Missourians".
"This is a very hard decision for me", McCaskill said, citing concern with Washington's polarized and vindictive politics. Joe Manchin (W.Va.) and Heidi Heitkamp (N.D.) - have said they will support Gorsuch, despite Senate Minority Leader Chuck Schumer's (D-N.Y.) push for Democrats to block an up-or-down vote on Trump's nominee.
"Senate Republicans are acting like if Gorsuch doesn't get 60 votes they have no choice but to change the rules", Schumer said.
"He can prove that he cares about the Senate by not changing the rules", Minority Leader Chuck Schumer of NY told The Associated Press, referring to McConnell. McCaskill's strongest opposition came based on the Endrew F. v. Douglas County School District case, in which Gorsuch sided with a Colorado school district and said it did not violate the Individuals with Disabilities Education Act because the student was making some progress.
Some Democrats have said Republicans "stole" a Supreme Court seat previous year when the Senate refused to consider Democratic former President Barack Obama's nominee to replace Scalia, appellate judge Merrick Garland.
McCaskill went on to voice her concerns that Gorsuch would take an activist approach where corporations have the same rights as people. Manchin said in a statement, "I hold no illusions that I will agree with every decision Judge Gorsuch may issue in the future, but I have not found any reasons why this jurist should not be a Supreme Court Justice".
"But Judge Gorsuch's nomination is about more than his incredible qualifications".
The Judicial Crisis Network, the out-of-state political action committee, has reportedly pledged to spend $10 million on ad buys targeting Tester, as well as Democratic Sens.
In the last 24 hours three other key red-state Democrats made public their position on President Trumps nominee to the high court.
Republicans, who have a 52-48 majority, need a total of eight Democrats to get to 60 - the critical number required to end the filibuster.
"I think it's really interesting that the Republicans wanted to out the fact that I was so honest about how torn I am", she added.
