The top US intelligence officer has denied a suggestion by the president-elect Donald Trump that US spy agencies leaked an unverified dossier containing damaging claims about him and Russia.
The Director of National Intelligence, James Clapper, says the leak is not a US Intelligence Community product.
Russia has once again denied allegations as unfounded that its officials had assembled a file of compromising information on US President-elect Donald Trump.
Russian Foreign Ministry Spokeswoman Maria Vladimirovna Zakharova described the dossier as being devoid of any evidence.
