GOP campaign arm pulls support of candidate who spoke against diversity 

Seth Grossman is running for New Jersey's 2nd Congressional District, where Republican Rep. Frank LoBiondo is retiring after holding the seat for 24 years.

He won the Republican primary in New Jersey, and the National Republican Congressional Committee initially endorsed his bid for Congress on June 6.

On Monday, the liberal media watchdog group Media Matters for America published a report that said Grossman had promoted opinion pieces from white nationalist websites.

"Bigotry has no place in society---let alone the U.S. House of Representatives. The NRCC withdraws our support of Seth Grossman and calls on him to reconsider his candidacy. The people of New Jersey's 2nd District deserve an inclusive Republican candidate who will be a trusted conservative voice in Congress," committee Chairman Steve Stivers said in a statement.

Grossman did not return a request for comment on the NRCC's decision.

A previous CNN KFile review of Grossman's social media posts revealed recurring rhetoric against diversity and derogatory descriptions of Muslims and African-Americans.

In one April 2015 Facebook post, Grossman shared a news article about Muslim migrants throwing Christians overboard from a refugee raft in the Mediterranean and added: "This is where 'multi-culturalism' and 'diversity' has taken us."

In December 2015, Grossman posted that Kwanzaa was "a phony holiday invented in 1960's by black racists to weaken and divide Americans during a Christmas season of joy and good will."

Grossman was also recorded calling diversity "a bunch of crap and un-American," which was uploaded to YouTube by the progressive "super" PAC American Bridge 21st Century.

"In my view, the best way to bring diversity to the Republican Party is for Republicans to openly say that the whole idea of diversity is a bunch of crap and un-American," Grossman can be seen saying in the video uploaded in June.

CNN has rated the race as leaning Democratic, and CNN previously reported it as a seat that Democrats see as a potential flip to win the House in November.
