"FACT is a much newer creation, organized in 2014 as a conservative counterweight to watchdog groups viewed as more left-of-center, such as Citizens for Responsibility and Ethics in Washington. The newer outfit took its first public action about a year ago when it filed a
complaint with the Federal Election Commission against Democratic voter data firm Catalist.
Since then, FACT has, on rare occasions (possibly just once), gone after a
Republican, but most frequently accuses Democrats —
particularly frontrunner and former Secretary of State
Hillary Clinton— of ethical or legal violations.
Its funding — $600,000 in 2014, according to the only tax return it has filed to date — comes entirely from a conservative donor-advised fund called
DonorsTrust, which means it could come from anywhere. DonorsTrust is a pass-through vessel that manages the charitable contributions of wealthy individuals and foundations to organizations that are “dedicated to the ideals of limited government, personal responsibility, and free enterprise,” according to
its website, while allowing the donors to remain anonymous. Charles Koch is among the many conservatives who have filtered money through DonorsTrust."
