A growing number of U.S. voters don’t want the Senate to confirm Supreme Court nominee Brett Kavanaugh, after he defended himself in public against sexual misconduct allegations, according to a new poll released Monday.

A Quinnipiac University National Poll released Monday said 48 percent of voters oppose Kavanaugh’s confirmation, up 6 points from a poll taken before to his appearance last week before the Senate Judiciary Committee. Support for the federal appellant judge rose slightly to 42 percent.
