Supreme Court nominee Elena Kagan says she considers recent high court decisions expanding gun rights to be "settled law."

Kagan was asked at her confirmation hearing about two recent decisions, including a 5-4 ruling Monday, which essentially guaranteed citizens' Second Amendment rights to have guns, no matter where they live.

Democratic Sen. Dianne Feinstein of California decried growing gang violence in her state, saying officials need leeway to deal with it.

Kagan responded that "once a court decides a case as it did, it's binding precedent." And she said judges must respect a precedent unless it proves unworkable or new facts emerge that would change the circumstances of a case.
