The DNC, as has been pointed out, did make a statement on their website. If something is not promoted on the internet or in public, it might as well not exist. That should have been learned from the last election.
This is a screenshot of what comes up when I Googled DNC statement on Marines and La protests:
If the DNC would actually pay to have their website up high in the search engine, their statement would able to be seen. The fact they don't understand this, means we need different people. The "picture of their statement" was sarcasm, since I couldn't find it, because the DNC doesn't pay to have their views publicized to the extent they must be.
I will say it again. I called a local news station and asked him how difficult it would be for a representative to get a press conference. They said all they would have to do is be invited and they would probably cover it. The reason we don't know about the DNC's views is due to negligence. And the time people have been arguing with me on this point, five Representatives could have gotten five press conferences.
