According to a senior Clinton campaign strategist who worked for Hillary in both her 2008 and 2016 presidential bids,
“Hillary approved Podesta’s decision to pay for the [Trump-Russia] dossier by funneling campaign funds through Marc Elias.
“The dossier was delivered to the Clinton campaign by [the opposition research firm] Fusion GPS in the summer of 2016, and Hillary read it and was thrilled by its salacious content.
“She bragged about it so openly that many of the people in her Brooklyn campaign headquarters were aware of the existence of the dossier. Hillary referred to it as her ‘secret weapon’ that would ‘blow Trump out of the water.’”
