Senate Minority LeaderMitch McConnell said on Sunday that he has not yet made a decision on whether to vote in favor of Jackson for the Supreme Court.
McConnell described his meeting with Jackson on positive terms but noted that he was going to pay close attention to her record during her confirmation hearing, which is slated to begin this week.
Jackson will be the first black woman to serve on the high court if she is confirmed.
Typically these Supreme Court nominees of both parties have never answered any of the questions, so I asked her after we had a good conversation in my office. He said that they typically say that something might come before him and that he doesn't want to judge how he might vote.
McConnell noted that while Supreme Court Justices Ginsburg and Breyer spoke out against court packing, Jackson did not make her feelings known about the issue during their discussion.
He said that the committee would ask her all the tough questions. I haven't made a decision on how I'm going to vote.
She will be treated better by the Democrats than Clarence Thomas and other Republican nominees have been. It will be a respectful, deep dive into her record which I think is appropriate for a lifetime appointment.
Thomas, who has served on the court since 1991, faced accusations of sexual harassment during his confirmation hearings.
Both men denied the accusations, but their confirmations were not well received by Democrats and liberal activists.
McConnell has been one of the most divisive figures in the modern history of the Senate.
He was the leader of the majority in the last year of Obama's presidency and blocked the president's nomination of Garland to the Supreme Court.
After the 2016 presidential election, McConnell opened the seat up for President Donald Trump to fill. At the time, the Senate was still controlled by Republicans.
After the retirement of Anthony Kennedy, Trump was able to appoint a new justice to the Supreme Court, Amy Coney Barrett, who was confirmed weeks after the death of Ruth Bader Ginsburg.
Many of the conservatives McConnell appointed to the federal bench were left open during the Obama years, which angered the Democrats.
Since President Joe Biden took office, the Senate Democrats have confirmed a record number of judges to the bench, the highest tally for a first-year president since Ronald Reagan in the early 1980s.
