According to court filings, he met with Steele at McCain's request, to view “the pre-election memoranda on a confidential basis."

Kramer then traveled back to the U.S. and gave copies of the memos to McCain, who in turn handed the documents over to the FBI. 

The committee interviewed Kramer last month prior to issuing a subpoena for him.

Republicans want to know if the document was used as the basis for a surveillance warrant on any members of the Trump campaign.

However, Democrats want to know if the salacious claims about Trump in the dossier, which connect him to Russia, are true.
