The story incorrectly reports the company was hired for the trump campaign to do data work.
As per https://youtu.be/yjn6wK01cqk?t=1878 only staff were hired.
I think the evidence is circumstantial but sufficient to warrant further investigation. CA harvested illegal data, used it in the Cruz campaign, lied about removing it and were then very involved in the presidential election, all within the span of a couple of years.
Parscape's denial is not in itself evidence, but I do agree with rsynnott that it's neither here nor there.
Specifically "which infamously used stolen Facebook data to target voters for President Donald Trump’s campaign in the 2016 U.S. election" from the article is inaccurate.
