Investigators do not believe Edward Snowden stayed at the Mira hotel in Hong Kong as he travelled from Hawaii to Russia last summer, but rather at the residence of a non-Chinese national, possibly a Russian, who is suspected of facilitating his travel to Moscow, a source familiar with the case tells Fox News.

The new allegation about Snowden’s contacts in Hong Kong comes as the leadership of the House and Senate intelligence committees also claimed the NSA leaker may have had help.

On the Sunday talk shows, the CIA’s former deputy director, Mike Morrell, along with Sen. Dianne Feinstein, the Democratic head of the Senate Intelligence Committee, for the first time publicly weighed in on that possibility — though neither pointed to specific evidence.

“The disclosures that have been coming recently are very sophisticated in their content and sophisticated in their timing, almost too sophisticated for Mr. Snowden to be deciding on his own,” Morrell told “Face the Nation.”
