Affidavit of Support related to change in Public Charge benefits

[Btranquilo 2]

I believe I understand correctly that a Lawful Permanent Resident who has been living in the US for more than five years and is eligible to receive SNAP (food stamps) benefits can now receive those benefits without the worry of having receipt of food stamps be an impediment to the approval of their application for Naturalization. Also, this individual also has a ten year old daughter who entered the US on a visa last month. I am the financial sponsor with an Affidavit of Support for both of them. 

My question is: "If the mother begins receiving Food Stamps for herself and her daughter am I, as the financial sponsor who signed the Affidavit of Support for both of them, potentially liable to have to repay the government for those food stamp benefits? Not sure it is relevant in which state the mother will be receiving food stamps; the mother and daughter are currently living in CA but are likely to move to Oregon. Thanks in advance for assistance on this topic.
