Confirmation hearings for Supreme Court nominee Judge Brett Kavanaugh opened on a contentious note Tuesday, with Senate Democrats raising noisy objections that much of Kavanaugh's lengthy paper trail is still off limits.

The hearing proceeded despite Democrats' call for delay. Republicans, who control the Senate, hope to confirm Kavanaugh in time to join the high court when its fall term begins next month, cementing a 5-4 conservative majority.

At 53, Kavanaugh would be the second-youngest member of the court and the second appointed by President Trump.

Sen. Chuck Grassley, R-Iowa, who chairs the Judiciary Committee, described Kavanaugh as one of the most qualified nominees he's ever encountered. The Yale law school graduate has spent 12 years on the federal appeals court in Washington, D.C., where he's authored hundreds of opinions.

"I don't want judges who always reach a liberal result or a conservative result. I want a judge who rules the way the law requires," Grassley said. "Judges must leave lawmaking to the Congress, the elected representatives of the people."

The hearing was repeatedly interrupted by protesters.

"What we've heard is the noise of democracy," said Sen. Dick Durbin, D-Ill.

Sen. Dianne Feinstein, D-Calif., the top Democrat on the committee, warned that Kavanaugh would tilt the high court to the right, especially on hot-button issues such as abortion and gun control.

"The president that nominated you has said, 'I will nominate someone who is anti-choice and pro-gun.' And we believe what he said," Feinstein said.

Feinstein was not reassured by Sen. Susan Collins, R-Maine, who said Kavanaugh told her that the high court's 1973 Roe v. Wade decision legalizing abortion is "settled law."

"The question is really do you believe that it's correct law," Feinstein said.

If history is any guide, Kavanaugh will offer few clues when the question-and-answer sessions begin on Wednesday.

"I don't decide cases based on personal or policy preferences," Kavanaugh will say, according to excerpts from his opening statement released by the White House, "I am not a pro-plaintiff or pro-defendant judge. I am not a pro-prosecution or pro-defense judge. I am a pro-law judge."

Democrats complained that the Trump administration blocked the release of more than 100,000 pages of documents detailing Kavanaugh's service in the George W. Bush White House. Other documents were released at the last minute, or not at all — including documents from 2003 to 2006 when Kavanaugh served as Bush's staff secretary.

"There's a 35-month black hole in your White House career where we've been denied access to any and all documents," Durbin said. "During that period of time, President Bush was considering same-sex marriage — an amendment to ban it — abortion, executive power, detainees, torture, Supreme Court nominees, warrantless wiretapping."

"Before sitting on the bench, you were a political operative, involved in the most political and partisan controversies of our time," added Sen. Patrick Leahy, D-Vt. "It is precisely those views that are being hidden from us today."

"I would think that anyone who wanted to sit on the nation's highest court would be proud of their record and would want the American people to see it," said Sen. Kamala Harris, D-Calif.

Sen. Ted Cruz, R-Texas, dismissed the complaints over missing documents as a distraction.

"There's an old saying for trial lawyers: If you have the facts, pound the facts. If you have the law, pound the law. If you have neither, pound the table. We're seeing a lot of table pounding this morning," Cruz said.

Sen. Mike Crapo, R-Idaho, agreed, calling Democrats' complaints "trumped up."

"Their motives are clear," Crapo said. "Use any means available to attempt to delay the confirmation process of a well-qualified jurist, fit for the job, indefinitely."

Durbin also questioned Kavanaugh's credibility.

During his confirmation hearing for the appeals court in 2006, Kavanaugh assured Durbin that he had not been involved in White House discussions of torture or the treatment of enemy combatants. NPR and the Washington Post later reported that Kavanaugh was involved in those discussions, offering counsel on how those policies might be judged by the Supreme Court.

"You are a committed textualist, Judge Kavanaugh," Durbin said. "If you are going to hold others accountable for their words, you should be held accountable for your own words."

Although Kavanaugh helped to investigate then-President Bill Clinton while working for independent counsel Ken Starr in the 1990s, he later wrote in a 2009 law review article that presidents' official duties are too demanding for them to be subject to such a probe.

"I believe it is vital that the President be able to focus on his never-ending tasks with as few distractions as possible," Kavanaugh wrote. He suggested that Congress excuse the president from both civil lawsuits and criminal investigations while in office.

Feinstein takes issue with that approach.

"He does not believe a sitting president should be investigated or prosecuted," she told reporters on a conference call last week. "In other words, the president is above the law."

Democrats say Kavanaugh's views on presidential immunity deserve special scrutiny now, given the ongoing investigation into Russian interference in the 2016 election by special counsel Robert Mueller, which has already implicated a number of Trump associates.

"This is a president who has shown us consistently that he is contemptuous of the rule of law," Durbin said at Tuesday's hearing, noting Trump's firing of former FBI Director James Comey and his repeated criticism of Attorney General Jeff Sessions.

"And it's that president who has decided you are his man. You're the person he wants on the Supreme Court," Durbin said. "So are people nervous about this? Are they concerned about it? Of course they are."

"We have to confront an uncomfortable but important question," Sen. Chris Coons, D-Del., added: "Whether President Trump may have selected you, Judge Kavanaugh, with an eye towards protecting himself."

Two Republican members of the committee who often criticize the president agreed that judicial independence is a particular concern in the Trump era, though they seemed less skeptical of Kavanaugh than their Democratic colleagues.

Sens. Jeff Flake, R-Ariz., and Ben Sasse, R-Neb., both pointed to Trump's tweet on Monday criticizing the Justice Department over the indictments of two "popular" Republican lawmakers, just ahead of the midterms.

"That is why a lot of people are concerned about this administration, and why they want to ensure that our institutions hold," Flake said.

"The comments from the White House yesterday, trying to politicize the Department of Justice, they were wrong and they should be condemned," Sasse added. "And my guess is that Brett Kavanaugh would condemn them."

The testy exchanges Tuesday morning highlight Democrats' lingering resentment over the treatment of former President Obama's last Supreme Court nominee, Judge Merrick Garland, who was never granted a hearing by Senate Republicans.

Kavanaugh, who serves alongside Garland on the D.C. federal appeals court, spoke highly of his colleague. describing Garland as "superb" in the excerpts of his opening statement.

Despite their concerns, Democrats have few tools to block Kavanaugh's path to the high court. A rule change last year allows the Senate to confirm a Supreme Court nominee with a simple majority vote.
