The Russian newspaper Kommersant reported Tuesday that President Vladmir Putin's spokesman Dmitry Peskov said the Russian government would consider any appeal from Snowden on its merits.
Snowden has said the he would seek asylum in Iceland or any country that would be willing to grant him that status. It's unclear if he has made an appeal yet.
A petition to the White House seeking a full pardon for Snowden had garnered more than 47,000 signatures by 11 a.m. today. Petitions with at least 100,000 signatures get a formal response from the White House.
The Justice Department has launched a criminal investigation into the leaking of the two documents. Formal charges are expected to be filed against Snowden soon.
Some U.S. officials say that some of Snowden's claims of obtaining far more classified information about government surveillance programs appear to be exaggerated.
A former federal prosecutor and the parents of a Navy SEAL member killed in action in Afghanistan filed a lawsuit against President Barack Obama, Verizon and others over the data breach. Several others, including some lawmakers have said they are considering similar lawsuits against the government.
