Ok, thanks for the reply.The group in question was reported to be in New York on December 13th as part of the Millions March NYC.
As you can see from that link, the event was organized and hosted by two women...Synead Nichols and Umaara Elliot. If you scan their website you will not see any claims of support from Al Sharpton or the civil rights group he founded, the National Action Network.
If you go to that site and check the press releases, you'll find in the second press release a name of all the official co-sponsors/organizers for the group. You'll again notice that Al Sharpton and/or the NAN are no where to be found on it.
Meanwhile, Sharpton was 225 miles away in Washington DC hosting his Justice for All March. This march was also on December 13th, the same day as the Millions March NYC, but in an entirely diffrent city.
You can google "National Action Network" and "Justice for All March" and find all sorts of links to instances on their website talking about the protest in DC they organized and hosted.
The only "evidence" that the New York crowd was in any way related to Sharpton has been:
1. Random right wing blogs that are either unsourced...OR the sources they link to actually don't verify any of the claims they make
2. Headlines or videos, such as a Fox and Friends video, where the NYC protests and the Al Sharpton protests are spoken about back to back giving the IMPRESSION they were directly related despite being entirely seperate events hosted by entirely different people.
