Senate Republicans have launched their attacks on Ketanji Brown Jackson, Biden’s Supreme Court nominee, before the President officially announced his pick on Friday, portraying her as a pawn of the Left.While Democrats praised the qualifications of Biden’s choice, potentially the first Black woman to serve on the court, Republicans criticized her record on crime and the support she holds from left-wing groups.Sen. Lindsey Graham of South Carolina, who voted for Jackson to serve as a judge on the US Court of Appeals for the District of Columbia Circuit eight months ago, appeared to unfavorably consider her nomination, saying in a tweet that “the radical Left has won President Biden over yet again.”The initial reaction to reports of the pick underscored the partisan nature of Supreme Court fights, far removed from those of two decades ago, when justices like the late Antonin Scalia and Ruth Bader Ginsburg were confirmed with little opposition in the Senate.Jackson, 51, currently sits on DC’s federal appellate court and had been considered the front-runner for the vacancy since Justice Stephen Breyer announced his retirement. Jackson worked as a clerk for Breyer, a federal public defender, an attorney in private practice, a federal district court judge and a member of the US Sentencing Commission.Breyer was confirmed in 1994 with 87 votes. Jackson will be fortunate to retain the three Republican votes she received last year from Graham, Susan Collins of Maine and Lisa Murkowski of Alaska, along with all 50 Democratic senators.While only a simple majority is necessary to confirm Supreme Court nominations in the 50-50 Senate, Republicans on the Senate Judiciary Committee could boycott a vote to stall the nomination. Iowa Sen. Chuck Grassley, the top Republican on the panel, has previously indicated to CNN, however, that he didn’t favor going that route.Many Republicans and conservative activists criticized Jackson on ideological grounds, arguing she is backed by progressives and far-left interest groups. Carrie Severino, president of the conservative group Judicial Crisis Network, said Jackson would be “a politician in robes.””We must not blindly confirm a justice to serve as a rubber stamp for a radical progressive agenda,” said Tennessee Republican Sen. Marsha Blackburn.Senate Minority Leader Mitch McConnell also noted in a statement that Jackson had “published a total of two opinions” since she was confirmed to her new post last year — even though she wrote more than 500 opinions in the eight years she spent on the district court — before turning to the broader party’s criticism. McConnell said she was “the favored choice of far-left dark-money groups that have spent years attacking the legitimacy and structure of the Court itself.”Read more about the GOP reactions here.
