HILLARY CLINTON’S presidential campaign funded research into the now infamous “dirty dossier” on President Donald Trump.

The Associated Press news agency said on Tuesday night that it had received a copy of a letter from an unnamed “person familiar with the matter.”

The letter detailed how Marc Elias, a lawyer for the Democratic National Committee (DNC) and Ms Clinton’s unsuccessful presidential campaign, and his legal firm Perkins Coie acted as a broker for the deal.
