Last week, the scf announced it would also run ads against House Republicans if they fail to embrace the right defund strategy.
As Cruz and Lee staged a filibuster-like marathon speech session Tuesday into Wednesday, the scf streamed them on its website.
BOLD Colors also includes Senate Conservatives Action, the super PAC affiliated with scf, as a client for $6,000 per month.
Many were also livid with Cruz for working with the scf when the group had attacked so many of the senators in the room.
The scf kicked in half of the $900,000 Bevin raised in the last quarter of 2014.
The August ads have left GOP senators furious with both DeMint and Sen. Ted Cruz, who starred in a number of scf ads.
