Sacramento, June 29 (RHC)-- Neo-nazi skinhead groups have promised to defend Donald Trump supporters at the upcoming Republican National Convention in Cleveland next month.  In an interview given to reporters with McClatchyDC, Traditionalist Worker Party spokesman Matt Parrott.

Earlier this year, Traditionalist Worker Party leader Matthew Heimbach had previously gained notoriety for assulting a young Black female protester while wearing a "Make America Great Again" baseball cap at a Trump rally in Louisville, Kentucky.

Parrot’s comments take place after his organization, described by the Southern Poverty Law Center as a white nationalist extremist group, staged a rally in Sacramento, California on Sunday, leaving 10 people injured.

The incident has fueled concerns about the potential for violent protests outside the major party conventions in Cleveland and Philadelphia this summer and in the run-up to the November 8th presidential elections.

In its "Intelligence Report," the Southern Poverty Law Center hinted at a possible correlation between the recent rise in extremism and the campaign rhetoric of presidential candidates like Donald Trump.

The report falls short of holding Trump directly responsible for the recent surge in hate groups, but says that his “demonizing statements about Latinos and Muslims have electrified the radical right.”
