"I was not involved in the contracting ... I was not involved in the hiring of this firm. I did not know about the existence of this contract," Brazile said in an appearance on ABC's "The View."
Brazile went on, "But if you asked me today, because I have a list of all the DNC consultants, do I see Fusion GPS? No. But if you ask me, was this a question [that] came up during my tenure as chair, it did on Nov. 4."
It was revealed last month that The Washington Free Beacon, a Republican-leaning publication, first hired Fusion GPS to produce the so-called Russian dossier on Trump.
Perkins Cole, a law firm that represented the Clinton campaign and the DNC, retained Fusion GPS in April 2016, two months before Brazile took over as chair.
The dossier, published in full by BuzzFeed last January, includes uncorroborated salacious allegations about Trump. He has denied the allegations and called the dossier fake news.
