Yeah, the above link you gave tells me that the Dems have been doing opposition research on Trump’s campaign managers and the one tasked to do that is Alexandra Chalupa.
But what’s so surprising? Campaigns do that to each other all the time....
The problem arises when we have the executive branch working in concert with a political campaign. We have wiretapping, the DOJ running investigations which can aid in opposition research.
