Ms. Guzman

“He also wanted to destroy protections for people with pre-existing health conditions, and to punish the people in advanced age with a cruel tax just because they’re this age.”

Uncertain and misleading.

Mr. Trump repeatedly has said he supported health care protections for pre-existing conditions, though he also has backed efforts to undermine them.

In the legislative debate over reforming health care, five major Republican proposals sought last year to repeal the Affordable Care Act.

Two would have retained the health care law’s prohibitions on insurers that seek to impose higher costs on patients with pre-existing medical conditions. The three others, including one drafted by Republican Senators Lindsey Graham of South Carolina and Bill Cassidy of Louisiana, would allow states to decide whether to enforce the prohibitions. All five proposals have either been rejected or are stalled in Congress.

In a Twitter post, Mr. Trump said in September that he “would not sign Graham-Cassidy if it did not include coverage of pre-existing conditions,” but erroneously added, “it does!”

No major health care proposals have included an explicit tax because of advancing age. What Ms. Guzman is likely referring to are price limits for insurers. Two of the Republican proposals sought to retain the health care law’s restrictions on charging older Americans more. The other three wanted to let states to waive the requirement.

It is inaccurate to call the easing of restrictions “a tax,” as it would be insurers — and not the government — that imposes and collects charges.

The change in “age rating” would not apply to Americans 65 and older who are covered by Medicare, nor those between 50 to 64 who have employer-sponsor insurance.
