The documents also showed commingling of personal and Foundation affairs, especially by former President Bill Clinton, according to The Hill.
The evidence was compiled by a firm called MDA Analytics LLC and included a submission by another whistleblower.
A spokesman for the Clinton Foundation said at the time: 'The Clinton Foundation has been one of the most heavily scrutinized charitable organizations in the world, and subjected to outrageous, politically motivated allegations that have been proven false time and time again.
'Critics continue to resurrect these false claims to try to damage the reputation of the Clintons and the Clinton Foundation.
'The fact is, the Clinton Foundation has demonstrably improved the lives of millions of people across America and around the world, while earning top ratings from charity watchdog groups in the process.'
Meadows has previously raised questions about a large drop in funds donated to the Foundation after Hillary lost her 2016 presidential race to Donald Trump.
Donations fell from $63 million in 2016 to $27 million in 2017.
He said: 'The remarkable significance of the drop in Clinton foundation donations raises grave concerns their operations were not above board as the American people have been led to believe.
'Whenever we look at the possibility of 'pay to play' by government officials, current or former, it demands answers--and anyone who uses public office to sell access for their own financial benefit must be held accountable.'
Meadows is a close ally of Donald Trump who has called for investigations into his former Democrat opponent.
The Clinton Foundation defended itself against the allegations, saying the fall in donations was due to the Clinton Global Initiative shutting down.
