U.S. Sen. Dianne Feinstein on Aug. 29, 2017 appeared at the Commonwealth Club in San Francisco, and said Donald Trump may be a good president over time. “The question is whether he can learn and change. If so, I believe he can be a good president.” She was booed at some stages of her talk with former Rep. Ellen Tauscher. She would not answer questions about whether she will seek re-election next year. Video courtesy of the Commonwealth Club.
