From the May 23 edition of CNN's Wolf:
WOLF BLITZER (HOST): He did promise during the campaign, and he tweeted this and he said it on many occasions, there would be no cuts to Social Security, no cuts to Medicare, no cuts to Medicaid. Let me show the tweet that he put up during the campaign: “I was the first & only potential GOP candidate to state there will be no cuts to Social Security, Medicare & Medicaid. Huckabee [referring to Mike Huckabee, who was then running] copied me.” Let's talk about those three promises. Social security. Any proposed cuts from the administration?
TAMI LUHBY: No. He is saving Social Security, or he's not touching Social Security. He's not touching Medicare. [OMB director Mick] Mulvaney said that he brought Trump a list of entitlement programs and Trump said “I'm not going to touch Social Security, I'm not going to touch Medicare, that's what I promised.” But when it comes to Medicaid, that was not as strong a promise on the trail. He kind of stopped promising that later in the campaign. And it's clear both from the GOP bills that's now in the Senate and from this budget that there are going to be big cuts to Medicaid.
BLITZER: Yeah, hundreds of billions of dollars in Medicaid. Although, that tweet specifically said not cuts to Social Security, Medicare, and Medicaid.
