Kavanaugh stops briefly to listen to Guttenberg and then turns away. He condemned the spate of USA school shootings but defended an opinion he wrote questioning whether semi-automatic rifles could be banned.
The hearing has strong political overtones ahead of the November election, but Democrats lack the votes to block Kavanaugh's confirmation. A video of the incident shows Perabo shouting, along with other protesters, during a meeting of the Senate Judiciary Committee in Washington DC.
Sen. Richard Blumenthal (D-Conn.) previewed one of the questions he was planning to ask when the hearing continued. "As a matter of the canons of judicial independence, I can't give you an answer on that hypothetical question", he said during the second day of his hearing before the Senate Judiciary Committee.
Harris said in her email that Kavanaugh puts "so many of our hard won civil rights - and the rule of law itself - on the line".
Lawyers who had argued cases in front of Kavanaugh recalled him as an active questioner from the bench, and a very well prepared jurist who would fit in on a Supreme Court whose justices are largely not shy in oral arguments with advocates. This sort of answer is consistent with the practices of past nominees, though it can be frustrating for both senators and legal commentators. President Donald Trump's nominee will be answering questions from members of the Senate Judiciary Committee.
"This is something I've never gone through before", Grassley acknowledged.
Ayanna Pressley defeats Dem Rep. Michael Capuano in upset primary victory
Pressley represents the latest underdog candidate to have emerged to challenge both establishment Democrats and Republicans. Michael Capuano has conceded to Boston City Councilor Ayanna Pressley in Massachusetts' Democratic primary .
Today marks the start of Judge Brett Kavanaugh's Supreme Court confirmation hearing as he faces questions from the Senate Judiciary Committee. Dianne Feinstein asking whether Nixon was "rightly decided". Kavanaugh promised a "completely open mind" if such issues came before him as a Supreme Court justice.
Liberals are concerned Kavanaugh could provide a decisive fifth vote on the nine-justice court to overturn the 1973 abortion ruling.
Kavanaugh noted that Roe was reaffirmed in a 1992 decision, Planned Parenthood v. Casey.
Most of us know that in 1973, the Supreme Court held in Roe v. Wade that states can not ban abortion before a certain point in pregnancy because doing so would violate a woman's constitutional right to liberty and privacy. In reaching this decision, the Court wrote that marriage is part of our right to liberty, explaining that "marriage is essential to our most profound hopes and aspirations". He said, seemingly approvingly, that Rehnquist found that a right to abortion was not "rooted in the traditions and conscience of our people", and that Roe was an example of "freewheeling judicial creation of unenumerated rights".
"Of course the violence in the schools is something we all detest and want to do something about", Mr Kavanaugh said, but added that handguns and other semi-automatic weapons were also used for hunting and self-defence.
The White House cited "constitutional privilege". And the stakes are so high that the party controlling the White House and Congress is rushing Kavanaugh towards the Court before the possible disruption of GOP plans by midterm voters. A few years later, in Pierce v. Society of Sisters, the Court found that an OR law requiring parents to send their children to public schools "unreasonably interfere [d] with the liberty of parents and guardians to direct the upbringing and education of children under their control".
Kavanaugh, who clerked for Supreme Court Justice Anthony Kennedy - whose coming retirement resulted in Kavanaugh's nomination by President Trump - has also been circumspect about the Affordable Care Act (ACA), neither rejecting nor endorsing the law.
