Politifact Reporter Chris Nichols explains what the fact-checking organization is on Insight to preview Thursday night's Political Junkie Meets Politifact California event at the California Museum.

Nichols will describe how a fact check is processed from beginning to end.

Joining Nichols is Angie Holan from the national Politifact office in Sacramento.

He'll also go over some recent fact checks including one about Dianne Feinstein claiming that the passing of Proposition 64 would mean prime time television ads about marijuana.
