Does it matter who paid for it?
That depends on your politics.
Republicans have criticized the dossier since it was first publicly disseminated when Buzzfeed published it in January. Mr. Trump has blasted it as “fake news” and “phony stuff,” and alleged that it is part of a broader witch hunt intended to cast doubt on his victory.
His allies now contend that the allegations in the dossier are discredited by the fact that it was funded at least partially by the Clinton campaign and the D.N.C. Mr. Trump asserted on Wednesday in an interview with Fox Business Network’s “Lou Dobbs Tonight” that the Democrats’ payments for the research were “the real collusion.”
Democrats argue that who paid for the research is irrelevant to the veracity of its claims, which they say should be thoroughly investigated. Yet some of the Democrats who funded the dossier have been leery about being associated with it. The lead Perkins Coie lawyer representing both the campaign and the D.N.C., Marc Elias, pushed back earlier this year when asked whether his firm was the client for the dossier, whether he possessed it before the election and whether he was involved in efforts to encourage media outlets to write about its contents.
On Tuesday, the veteran Democratic consultant Anita Dunn, who is working with Perkins Coie, explained Mr. Elias’s earlier response. “Obviously, he was not at liberty to confirm Perkins Coie as the client at that point, and should perhaps have ‘no commented’ more artfully,” Ms. Dunn wrote in an email.
