The White House released both sets of the forms Saturday as part of broad release of documents a detailing the financial holdings of top administration officials.
Flynn's initial form was submitted to the Office of Government Ethics and the White House on Feb.11 - just days before he was forced to leave his post amid controversy over his contacts with Russia's ambassador.
Flynn later noted the payments on an amended form he signed Friday that listed among his sources of income the Russian government-backed television network RT, a U.S. air cargo company affiliated with the Volga-Dnepr Group and the U.S. subsidiary of Russian cybersecurity firm Kaspersky Lab.
As Flynn's disclosure shows, he earned at least $1.3 million in the past year, including more than $827,000 through his consulting firm, Flynn Intel Group.
