It's been a big weekend for the Ku Klux Klan, the United States' oldest hate group.
While three counter-demonstrators were stabbed at a rally in Anaheim on Saturday, Donald Trump also brought headlines to the group by refusing to condemn an endorsement from a former KKK leader.
When asked on CNN if he would distance himself from an endorsement by David Duke, a former grand wizard of the group, Trump said:
I don't know anything about David Duke. I don't know what you're even talking about with white supremacy or white supremacist. I don't know. I don't know, did he endorse me, or what's going on?
When it was clarified that the news anchor was asking about "David Duke and the Ku Klux Klan", Trump replied:
Honestly, I don't know David Duke.
Trump later tweeted a video saying he disavowed the former leader's endorsement on Friday, blaming a faulty earpiece.
According to the Southern Poverty Law Center (SPLC) there were 190 Ku Klux Klan chapters in 2015, an 18 per cent increase on the previous year.
However, three fewer states had chapters in 2015, a total of 36.
The SPLC estimates that the KKK has between 5,000 and 8,000 members in the US today.
Note: There are no chapters in Alaska or Hawaii (not shown on map)
The total number of 190 KKK groups does not include 94 Neo-Nazi groups, 95 White Nationalist groups, 95 Racist Skinhead groups, or 35 Neo-Confederate groups.
The overall number of hate groups has been rising dramatically since the turn of the century, according to the SPLC.
In 2015 the SPLC documented 892 hate groups, a 14 per cent increase from in 2014.
