On July 9, Senator Elizabeth Warren (D-Mass.) issued a tweet warning the American public that President Donald Trump’s shortlist of U.S. Supreme Court nominees has been “pre-approved by right-wing extremists."

Referring to the potential nominees, including Amy Coney Barrett, Raymond Kethledge, Brett Kavanaugh, and Thomas Hardiman, Warren stated that “they've shown their willingness to side with the wealthy & powerful over the rights of women, workers, voters, & minorities. But we're ready to fight back.”

In an interview with MSNBC’s Chris Hayes, Warren expressed her concerns over the president’s interest in nominating a conservative to fill Justice Anthony Kennedy’s vacancy.

“Donald Trump has already said that that he’s going to pick somebody who has been prescreened off a list that was put together by a group, whose number one job, an extremist group, is to make sure that Roe v. Wade gets overturned," she said. "This means that he’s looking for a nominee who will criminalize abortion and try to punish women.”

“This is about voting rights, whether or not democracy fundamentally works in this country,” cautioned Warren. “Justice Kennedy has been the swing vote. He was the one who helped stand up for equal marriage.”

“All of that is now at risk when Donald Trump gets to replace the swing vote with somebody off a preapproved extremist list,” said the senator.

President Trump and many Republicans are eager to fill the Supreme Court vacancy before the 2018 mid-term elections, which will be held in November. After just 12 days of deliberations, Trump is set to announce his nominee on Monday at 9 p.m. EDT.
