Schumer also laid into Trump's judicial adviser, Leonard Leo of The Federalist Society, who helped compile a list of 25 possible candidates for the SCOTUS justice.
On Monday, Trump phoned Justice Kennedy to inform him that his former law clerk would be nominated to fill his seat.
If confirmed, Trump's choice would solidify the high court's conservative majority and continue the president's push to shift the federal bench to the right. Judge Amy Coney Barrett is the favored nominee among the religious right. Todd Young, R-Ind., said in a statement shortly after Trump's announcement.
He is a graduate of both Yale undergrad and law school, and he clerked for Kennedy.
When Trump nominated Justice Neil Gorsuch in 2017, he faced an intense backlash from liberal activists and fielded a barrage of hostile questions from Democratic senators during his confirmation hearings.
Hirono's comments come in contrast to what other Senate Democrats have said of the nominee. Senate Republicans hold only a 51-49 majority, leaving them hardly any margin if Democrats hold the line.
Casey is one of the handful of so-called "Red State" Democratic senators who are running for reelection in a state carried by the president in the 2016 election, and who are seen as especially vulnerable this election cycle as a result.
Trump has been struggling with Kavanaugh's association with the Bush family, however, an issue the Post calls the "Bush factor". At the top of that list is abortion. Even though he previously wrote against a woman's right to have an abortion in a case, he has never issued any public opinion on whether or not Roe v. Wade is settled law. CBS also reports he is a staunch supporter of Second Amendment.
President Donald Trump has decided on his nominee to the Supreme Court after spending Monday morning working the phones primarily seeking input about two judges who were said to be the finalists, Brett M. Kavanaugh and Thomas M. Hardiman, people familiar with the discussions said. He is hoping to replicate his successful announcement of Justice Neil Gorsuch past year.
"Trump has enjoyed teasing details of his process in recent days, saying Thursday that he was down to four people and 'of the four people, I have it down to three or two".
The real players are folks like Senate Majority Leader Mitch McConnell, whose late-hour political jockeying upended the notion that the high court spot was D.C. Circuit Court of Appeals Judge Brett Kavanaugh's to lose. With Kavanaugh a mere 53 years old, he could serve for a generation or more. He also was a key aide to Kenneth Starr during Starr's investigation of President Bill Clinton, worked on behalf of George W. Bush's campaign during the election recount in 2000 and served in the Bush White House.
The White House invited a number of senators to attend the Monday night announcement.
Senate Democrats are sure to press Kavanaugh to explain his views on investigating and impeaching a president based on allegations of lies and a cover-up, something that could prove uncomfortable for Trump given the investigation under way by special counsel Robert S. Mueller III.
Barrett spent much of her career as a law professor at the University of Notre Dame and has served as a judge for eight months, which gives her the least experience of any of the potential nominees.
"It should go through; the Republicans are in control of the Senate, and we all know how important this is", Hatch said.
Still, ultra-conservative purists distrust Kavanaugh.
McConnell reportedly spoke often to Trump and White House general counsel Don McGahn throughout the selection process and was anxious about the vast number of documents Kavanaugh had amassed during his 12 years on the D.C. appeals court could prove problematic.
