McClintock said the amnesty would enable Snowden to return to the United States to answer questions about his leaking of government secrets "without the threat of prosecution."
"We have some very good laws against sharing secrets and he broke those laws," McClintock said last week in an interview with KCRA-TV last week after a town hall in Roseville, near Sacramento.
"On the other hand, he broke them for a very good reason because those laws were being used in direct contravention of our 4th Amendment rights as Americans."
Snowden, a former NSA contractor, has been granted temporary asylum in Russia after disclosing agency surveillance programs. His actions have prompted President Obama to propose reforms in the agency's spy programs.
Snowden has been viewed as a heroic whistleblower by his supporters and called a traitor by his critics.
