WASHINGTON — Pressured by Democrats with Donald Trump on their minds, Supreme Court nominee Brett Kavanaugh rejected repeated efforts at Wednesday’s Senate confirmation hearing to reveal his views about a president pardoning himself or being forced to testify in a criminal case.

For a second day, the judge nominated by Trump insisted to probing senators that he fully embraced the importance of judicial independence. But he refused to provide direct answers to Democrats who wanted him to say whether there are limits on a president’s power to issue pardons, including to himself or in exchange for a bribe. He also would not say whether he believes the president can be subpoenaed to testify.

“I’m not going to answer hypothetical questions of that sort,” Kavanaugh said in response to a question from Sen. Patrick Leahy of Vermont about pardons. Still, he began his long day in the witness chair by declaring that “no one is above the law.”

The Senate Judicial Committee hearing has strong political overtones ahead of the November congressional elections, but as a practical matter Democrats lack the votes to block Kavanaugh’s confirmation.

They are concerned that Kavanaugh will push the court to the right on abortion, guns and other issues, and that he will side with Trump in cases stemming from special counsel Robert Mueller’s investigation of Russian interference in the 2016 election and possible ties to the Trump campaign. The 53-year-old appellate judge answered cautiously when asked about those most matters.

Protesters continued their efforts to interrupt the hearings, but senators basically ignored their shouts as they were removed by police. Democrats’ complaints also persisted that they were being denied access to records from Kavanaugh’s time in the George W. Bush White House.

One TV viewer gave Kavanaugh a rave review.

Trump said he had been watching the hearings and thought the Democrats were “grasping at straws” in questioning the man he chose to replace retired Justice Anthony Kennedy. He said he “saw some incredible answers to very complex questions.”

The committee’s top Democrat, Dianne Feinstein of California, disagreed. “He’s not being very specific,” she said during a break in the proceedings.

The Democrats weren’t the only ones who recognized the importance of questions about Trump and the Russia investigation. Committee Chairman Chuck Grassley, an Iowa Republican, asked Kavanaugh right away whether he would be independent from the president who chose him for highly prestigious lifetime position.
