While searching for campaign contributor and recipient data… I found this .gov database:

https:// www.fec.gov/data/receipts/individual-contributions/?two_year_transaction_period=2018&min_date=01%2F01%2F2017&max_date=12%2F31%2F2018'

Join in the fun if interested. I've just begun searching this to see if it produces any helpful leads for us…Hoping to find cross-references to resignations and firings of CEOs/Presidents.
