Story highlights Patagonia and the spokeswoman for the Interior engaged in a heated Twitter spat

Washington (CNN) Outdoor retailer Patagonia and the Interior Department continued their public spat over US national monuments Tuesday on Twitter, trading barbs over each others' ties to "special interests."

The company announced Tuesday that it plans to take legal action over President Donald Trump's move to dramatically shrink two national monuments in Utah, a move that Interior Secretary Ryan Zinke recommended.
