(5 Sep 2018) Supreme Court nominee Brett Kavanaugh says a 1973 Supreme Court decision that established a constitutional right to an abortion is an "important precedent" that has "been reaffirmed many times." Kavanaugh was asked about the Roe v. Wade ruling by Democrat Dianne Feinstein of California. He said the decision has "been reaffirmed many times over the past 45 years." And he noted that a 1992 decision of the court called Planned Parenthood v. Casey didn't just reaffirm Roe v. Wade in passing. He said that decision becomes "precedent on precedent." Kavanaugh compared the Roe decision to another case, Miranda v. Arizona, which requires law enforcement to tell suspects their rights. Kavanaugh noted that former Chief Justice William Rehnquist had been a critic of the Miranda decision but later upheld it as precedent. Kavanaugh also refused to say whether a president can be forced to testify in a criminal case, calling it a hypothetical. The topic is front-and-center at Kavanaugh's hearing because the man who nominated him, President Donald Trump, could face a subpoena in special counsel Robert Mueller's investigation. Sen. Feinstein asked Kavanaugh whether he thinks a sitting president can "be required to respond to a subpoena." Kavanaugh responded: "I can't give you an answer on that hypothetical question." The Supreme Court has never ruled on a presidential subpoena.
