Republican and Democratic senators on Sunday drove home their parting messages for the Supreme Court nomination of Judge Brett Kavanaugh, making clear the stakes when Kavanaugh sits before the Senate Judiciary Committee this week.

“If you are looking to a Republican president to pick a qualified conservative, he would be on the top of anyone's list,” Sen. Lindsey Graham Lindsey Olin GrahamSenate GOP aims to confirm Trump court pick by Oct. 29: report The Hill's Campaign Report: GOP set to ask SCOTUS to limit mail-in voting Senate GOP sees early Supreme Court vote as political booster shot MORE (R-S.C.) said on “Fox News Sunday," predicting that as many as 55 senators will vote to confirm Kavanaugh if he performs well at Tuesday's hearing.

“He's the one person I think every Republican president would see is the most qualified of their generation,” he added.

Senators took to the Sunday talk shows to preview their arguments for Tuesday's hearing. Republicans sought to cast Kavanaugh as a capable and qualified nominee, while parrying away a litany of Democratic arguments for why the Senate should reject Kavanaugh or delay his confirmation process entirely.

Chief among those issues on Sunday was the subject of transparency.

"You have a nominee with excellent credentials, with his family behind him, you have the cameras there, you have the senators questioning, but this isn’t normal because we are not able to see 100,000 documents that the archivist has just — because the administration has said we can’t see them," Sen.

She noted that there are close to 150,000 confidential documents she's been able to see, but that are restricted from the public. Asked if anything she's seen makes Kavanaugh unqualified for the job, Klobuchar said the documents "strongly bolster the arguments that I could make."

"I think you could ask some very interesting questions about these documents, that I'm unable to even say because I'm not able to make them public," Klobuchar said.

Bush administration.

"If [Kavanaugh's] so proud of his conservative credentials, show us the record, stand before us, trust the American people and they will trust you," Durbin said on "Fox News Sunday."

The White House and Senate Republicans have countered the long-standing Democratic argument about a lack of disclosure by noting that they've released hundreds of thousands of documents related to Kavanaugh's past work.

Republicans have asserted that Democrats have latched onto complaints about Kavanaugh's paperwork because they've been unable to gain traction on a policy issue that could endanger his nomination.

"There is a serious question as to whether this president, given the opportunity, will end the Mueller investigation, something which most Republicans and the overwhelming majority of Americans say would be a serious mistake," Durbin said. "And we ask, of course, Judge Kavanaugh, 'what do you think,' and he says it's hands off when it comes to a president during his term in office."

"I think that's a mistake and it's one of the major reasons people had misgivings about his nomination," Durbin added.

Republicans on Sunday rejected the idea that Kavanaugh would be in Trump's pocket on any potential ruling over a Mueller subpoena or other investigative issue.

A final central argument in Kavanaugh's nomination has been the fate of Roe v. Wade. Since the time former Justice Anthony Kennedy announced his retirement, Democrats and pro-choice advocates have warned that Trump would seek to nominate a judge to overturn the landmark case that guaranteed a woman's right to an abortion.

While Durbin reiterated that message on Sunday, Republicans downplayed the need for Kavanaugh to address his thoughts on the case explicitly ahead of Tuesday's hearing.

Gorsuch was Trump's first successfully confirmed Supreme Court appointee.

"With regard to Roe v. Wade, I didn’t get into the details when I met with him about asking about that," Sullivan added. "I think he’s going to be asked about this a lot during the whole week so we’re going to watch on that."

Wade as settled law, Graham argued Kavanaugh would not be doing his job if he had such a closed-minded approach.

"Precedent is important, but it's not inviolate," Graham said on CNN's "State of the Union."

"If it were up to me, states would make these decisions, not the Supreme Court," he added. "But it is a long-held precedent of the court. It will be challenged over time, and I hope he will give it a fair hearing, and I know he will."
