Leaving aside the specific politics of their answers, my overall impression was that Obama administration treated Whitehouse petitions more like a minor sideshow than anything else. Writing less than committal responses to ones that legally required a response, but not really using them as a tool of governance. Just to be clear, that's my personal impression and may not be supported by actual reality of what went on in the administration.
Did Donald Trump's administration indicate their opinion of whitehouse.gov petitions? Do they plan to take them seriously as input or indicator of public mood? Ignore? Aren't even aware of that thing?
