Trump became the GOP nominee in 2016 by breaking from party orthodoxy in opposing entitlement reform. Then he was president for four years and didn’t touch medicare or social security. So yes, I’m going to trust that over the same people who told me in 2016 that there would be Muslim internment camps.
Trump did nothing but increase taxes on the poor and decreased them for the rich in his first term because he had no plan. Now the plan is project 2025, which he pretended to not be aware of or have anything to do with, so not sure why you would trust anything he says.
