House Minority Leader Nancy Pelosi (D-CA) called for revisiting U.S. policy on nuclear weapons in her press briefing Thursday.

“There is interest in the U.S. establishing itself as no first use, no first nuclear use,” she told reporters, saying it would be a bipartisan effort. She said the first use policy was established in 1946 when it was “a different world” and the idea of changing it has been around for a while.

“I put this in the category of urgent,” she said. “We take an oath to protect and defend, and the law under which the president of the United States has authority to exercise first use is one that is ancient.”

“There are all kinds of proposals out there, one saying, declaring the United States of America will not engage in first use of a nuclear weapon,” she continued. “I like that one best.”
