The president's confusion (lies) grows and spreads to administration staff.

NBC News’ Kristen Welker on Wednesday interviewed Mehmet Oz — the former talk show host and heart surgeon who now runs the Centers for Medicare and Medicaid Services...where she "aired a montage of Trump making the boasts, including promises to slash costs “by 1,200, 1,300, 1,400, 1,500%,” even though, as critics have repeatedly pointed out, it would essentially make medications free or even see people being paid to receive them."

"Oz creatively replied: “The president does the calculation by saying, ‘OK, if a drug was $100 and you reduce it to $50, it’s 100% cheaper because you’re taking $50 off and left with only $50, so the amount you took off the price is equal to the amount that’s left. They’re equal, so it’s 100%.’”

"Welker pointed out that Trump has boasted about reducing drug prices by up to 1,500%. Oz fired back: “Well, if you take a drug that is $200 or $240 like we did last week and reduce it to $10, those are the numbers you’re talking about.”
