The Trump administration made the statement about the numbers of women potentially affected completely on supposition, with no evidence whatever.  It's referencing a future action of millions of employers without any substantive history relative to associated past action or known intention.  In other words, complete fabrication, following in its leader's footsteps. Or lips. 

Given those who have already sued for exemption, I see the pattern of change affecting women in lower-wage jobs.  Religious and health care organizations are not known for their generosity in compensation, and smaller businesses which may be inclined to force their morality on others are also likely counting payroll pennies.  One more takeaway chalked up on the board in the name of "freedom."
