I can only find opinion pieces and no official republican statement promising they would cut social benefits. In any case I believe those are empty electoral promises. In my country the right wing campaigned on the promise of cutting social benefits, now that they are ruling they simply can't do it unless they want a rebellion. That's because we are in such a bad situation since we blindly followed the orders of our master Biden. The US is also in a bad place after the delusional democrat foreign policy, the last thing the republicans could do now is cut social benefits at a time where quality of life standards are dropping for everyone. Again, thanks to the bankrupt policies of your governments.

Multiple republicans have said they will not support raising the debt ceiling unless Medicare/social security receive cuts. Smith and Arrington I think? Pretty sure I was reading about them and other members of the house vocalizing this just a few weeks ago.
