Progressive candidates hope to fill Sen. Feinstein's seat amid continued calls to resign

Progressive left-wing politics took center stage online Thursday at a Senate candidate forum. Rep. Katie Porter and Rep. Barbara Lee answered questions about why they should fill Sen. Dianne Feinstein's seat at the end of her term. Meanwhile, Feinstein at 89 and the oldest sitting Senator, returned to Washington this week amid questions about her declining physical and mental health.
