(Thursday, December 10, 1992, 10:27 a.m. EDT) — Sen. Bob Packwood of Oregon said today that he took “full responsibility” for his “unwelcome and offensive” sexual advances toward female aides, but declined repeatedly to describe his behavior.

Moreover, the 60-year-old Oregon Republican, who was elected to his fifth term last month, declared at a news conference that he would not resign. “I’m not going to resign under any circumstances,” he said.

Some women’s groups in Oregon asserted that they found the Senator’s performance more an act of political expediency than one of contrition.

Holly Pruett, executive director of the Oregon Coalition Against Domestic and Sexual Violence, said in a telephone interview from Portland, “While using a masterfully crafted statement to make it appear as though he was taking accountability, clearly he has no ability to distinguish right from wrong.” Questioned on Specifics

In his first public appearance in more than two weeks, the 60-year-old Senator called his conduct not merely inappropriate, stupid or boorish, but “just plain wrong.” (click here to watch video of KATU-TV’s 5 p.m. PDT news broadcast, covering the Packwood news conference).
