Senator Mitch McConnell, the majority leader, said the bill would “reduce taxes on the middle class,” but most of the benefits go to high-income earners.

The budget office estimated that the bill includes tax cuts totaling $700 billion over the next decade. People at all income levels would see some of the money, but characterizing the cuts as a boon for the middle class is misleading.

More than $230 billion comes from repealing two taxes that apply only to individuals making over $200,000 a year. The bill would also eliminate a tax on health insurers, amounting to a cut of $145 billion.

Middle-class households would see an average tax cut of $280, according to the nonpartisan Tax Policy Center. In contrast, a household in the top 0.1 percent would get a cut of $250,000. Looking at overall distribution, two-thirds of the $700 billion would line the pockets of the richest one-fifth of Americans.

The White House and President Trump used a flawed report to claim the Affordable Care Act led to premiums’ doubling and tripling.

A reader asked The Times to check a graphic circulated in the White House’s newsletter, Your 1600 Daily, stating that premiums “are up by 105 percent” since the A.C.A.’s enactment. Mr. Trump later bemoaned a 206 percent (actually 203 percent) increase in Alaska specifically.

The figures come from a May report from the Department of Health and Human Services that said premiums increased to $476 this year from $232 in 2013, before the health care law took full effect. According to the report, average premiums in Alaska jumped to $1,041 from $344.

As The Times explained in a fact-check of Mr. McConnell, the comparison is imperfect — and Mr. Trump errs further by selectively choosing the second-highest increase to exaggerate the report’s findings.

Mr. Trump compares two fundamentally different universes of plans: all the plans on the individual market in 2013 and those only on the federal exchange in 2017. The plans are different, with Affordable Care Act plans covering more and sicker people and offering more comprehensive benefits.
