J. Scott Applewhite / AP / File California Politifact Reporter Chris Nichols joins us on Insight tonight to examine a hazy claim by U.S. Senator Dianne Feinstein stating that Proposition 64 would lead to prime time marijuana advertisements. Nichols gives this claim a "Mostly False" rating because of the misleading way she said it. Had she said Prop 64 paved the way for television ads, he says it would be more accurate a statement.
