Roy Blunt said on Sunday that he wouldn't vote to confirm Judge Jackson to the Supreme Court, but that she would get the necessary votes in the upper chamber to be approved.

During an interview on ABC's This Week, the retiring Missouri Republican who had been seen as a potential swing vote said that Jackson was certainly qualified, but that he had concerns about her.

I think she has a great personality. I think he will be a good colleague. The judicial philosophy is not about looking at what the law says and applying that, but about looking at the Constitution as a more flexible document, and even the law. He told George Stephanopoulos that there are cases that show that.

I think she will be confirmed. I think it will be a high point for the country to see her on the court, but I don't think she is the kind of judge that will do the kind of work that needs to be done.

He told Politico last month that he wanted to support the nomination, but would make his decision based on judicial temperament.

I would like to vote for the first Black woman to go on the court, but I would have to look at her view of what the court does.

While on This Week, he said that despite his no vote, he recognized the significance of Jackson's milestone.

He told Stephanopoulos that he wouldn't be supporting her, but would be joining others in understanding the importance of the moment.

Jackson, who was confirmed as a judge on the US District Court for the District of Columbia, was nominated by President Joe Biden to the high court in February after Justice Stephen Breyer announced that he would step down from the Supreme Court at the end of the current term.

Jackson is set to be confirmed later this week with the support of Republican Sen. Susan Collins of Maine.
