John Podesta said he has no idea whether intelligence agencies asked Democratic National Committee officials for their Russian-hacked servers or whether they turned them over for investigation.
"That was a matter for the DNC," the former Clinton campaign chairman told host Maria Bartiromo.
Podesta insisted he fulfilled his obligations by turning over Hillary Clinton's private servers, which were suspected to be vulnerable to hacks by Russia or others.
A year ago the FBI concluded that while Clinton and her associates had been "extremely careless in their handling of very sensitive, highly classified information," they did not "intend to violate laws."
The head of the failed campaign called the FBI's approach to the DNC Russia hack "fairly casual" and "lackadaisical."
"If anything, it's on the FBI that didn't come forward and really inform the DNC about what was going on until long after," Podesta stated.
