“We expect the Russian government to look at all options available to expel Mr. Snowden back to the U.S. to face justice for the crimes with which he is charged,” the White House National Security Council spokeswoman Caitlin Hayden stressed. Earlier, the US strongly objected to the authorities in Hong Kong and China at the decision to let Snowden flee through their territories. The US Justice Department has been in “continual contact” with Hong Kong authorities since the prominent whistleblower Edward Snowden first revealed his identity and whereabouts on June 10, Reuters reports. Hong Kong did not raise any issues in regard the sufficiency of the documents provided with the US request for Snowden’s arrest, the official claimed. “In light of this, we find their decision to be particularly troubling,” the official said.

In Sunday’s press release however, announcing that Snowden has left Hong Kong, the island government acknowledged that the US was aware of discrepancies as they had filed a request for more information. “Snowden left Hong Kong …on his own accord for a third country through a lawful and normal channel… [as there was] no legal basis to restrict Mr Snowden from leaving,” the release read. Earlier the US State Department issued a statement warning the countries of the ‘Western Hemisphere” about reports that Edward Snowden might be looking refuge in the region and urging them to not let the whistleblower in and assist with returning him to the US. “The US is advising these governments that Snowden is wanted on felony charges, and as such should not be allowed to proceed in any further international travel, other than is necessary to return him to the United States,” the official said as cited by Reuters. The announcement by the Justice Department came as US authorities revoked Snowden’s passport, according to several US officials who spoke with the media on condition of anonymity. “As is routine and consistent with US regulations, persons with felony arrest warrants are subject to having their passport revoked,” Jen Psaki, State Department spokeswoman said in a statement. “Such a revocation does not affect citizenship status. Persons wanted on felony charges, such as Mr. Snowden, should not be allowed to proceed in any further international travel, other than is necessary to return him to the United States. Because of the Privacy Act, we cannot comment on Mr Snowden’s passport specifically.” On Sunday, WikiLeaks which is allegedly helping Snowden escape the American justice system tweeted Snowden left Hong Kong and is “bound for the Republic of Ecuador via a safe route for the purposes of asylum.” En route to his final destination, whistleblower Edward Snowden made a stopover at Moscow’s Sheremetyevo airport. Due to the absence of a Russian visa, he allegedly stayed overnight in a hotel in the airport’s transit zone. On Monday, he is expected to fly to Cuba before changing planes to Ecuador. Snowden has been charged by the US authorities with theft of federal government property, unauthorized communication of national defense information and wilful communication of classified communications intelligence to an unauthorized person. The last two charges fall under the US Espionage Act.
