WASHINGTON — At a Wednesday afternoon rally in Missouri, President Trump played up what he called the “biggest tax cuts in history” and boasted about economic growth “in a nonbraggadocious way.”

“In fact, they’re going to say Trump is the opposite of an exaggerator,” he said of his rosy projections, in a speech full of exaggerations and falsehoods. Here’s an assessment.

He is wrong that “for years, they haven’t been able to get tax cuts, many, many years since Reagan.”

President Ronald Reagan, who enacted a major tax cut in 1981 and lowered tax rates again in 1986, was hardly the last president to have done so. President Bill Clinton signed the Taxpayer Relief Act of 1997. President George W. Bush enacted two major tax cuts in 2001 and 2003. The stimulus passed under President Barack Obama included hundreds of billions of dollars in tax cuts, and Mr. Obama later extended the Bush tax cuts with the American Tax Payer Relief Act of 2012.

He inaccurately suggested the plan wouldn’t help the wealthy.

Mr. Trump insisted that the tax bill is “not good for me” or the wealthy. Referring to Senator Chuck Schumer, Democrat of New York and the minority leader, the president said: “I keep hearing Schumer, ‘This is for the wealthy!’ If it is, my friends don’t know about it.”
