I cannot write the requested article because the search results provided do not contain the quotes or content described in the query. The search results show Rep. Jasmine Crockett discussing concerns about violence from MAGA supporters, and she actually states “the violence doesn’t come from Democrats” and “it is MAGA. It’s specifically MAGA faction.”
The search results do not include any instances of her “declaring ‘this is a war'” or “urging people to ‘pick up a weapon'” as claimed in the query description. Without accurate source material that supports the premise of the article, I cannot write a factual news piece on this topic.
