John Fitzgerald secured one of the top two spots in California's "jungle" primary system last month, where the top two vote-getters regardless of party affiliation advance to the general election.
Fitzgerald is slated to face off against incumbent Democratic Rep. Mark DeSaulnier in November in the reliably blue district near San Francisco.
Fitzgerald included calls on his campaign website for people to note "Jewish supremacism" and said last week on a radio show hosted by an anti-Semitic commentator that "everything we’ve been told about the Holocaust is a lie," according to The Times.
The candidate told The Times this week that the Holocaust was a "complete fabrication" and placed blame for the Sept. 11, 2001, terror attacks on the Israeli government.
