In the same time period, President Franklin D. Roosevelt began public works projects in response to the Great Depression, Mr. Obama had enacted a stimulus package to counter the financial crisis, and President George W. Bush had signed major tax cuts.
He falsely claimed the United States is âthe highest-taxed nation in the world.â
In 2015, the United States ranked in the middle or near the bottom compared among 35 advanced economies in the Organization for Economic Cooperation and Development by the typical metrics: No. 28 for total tax revenue as a percentage of gross domestic product, No. 22 for corporate tax revenue as a percentage of G.D.P. and No. 13 for tax revenue per capita.
He misrepresented the trend in home building.
Contrary to Mr. Trumpâs claim that âhomebuilders are starting to build again,â construction hit an eight-month low in May and was 2.4 percent lower compared to May of last year. The number of units authorized by permits, too, have fallen since January and declined by 0.8 percent compared to the same time last year.
He falsely claimed that an Obama-era rule applied to âa little puddle in the middle of their field.â
Mr. Trump rolled back a rule that limits pollution in the countryâs waters. But that rule explicitly excludes puddles and most ditches, and it really only applies to streams and rivers that drain into major bodies of water.
He falsely claimed Gary Cohn paid â$200 million in taxesâ to serve as his economic adviser.
Mr. Cohn, the former president of Goldman Sachs, was required to divest company shares under ethics laws, and sold about $220 million worth of Goldman stock. He also received a cash payout of about $65 million. The nearly $300 million payout is, of course, eventually subject to taxation but characterizing it as money paid to the I.R.S. is not accurate.
He exaggerated the increase in military spending as âhistoric.â
Mr. Trump proposed to add $52.8 billion to the Pentagonâs budget, which amounts to nearly a 10 percent increase. There have been at least 10 larger increases to the base defense budget since the 1977 fiscal year and four since 2002.
Factoring in war spending, Mr. Trumpâs claim is even less credible. There have been 27 years since 1940 in which the military spending was as high or higher than the proposed increase. As a percentage of gross domestic product, there have been roughly 35 years in which military spending matched or surpassed Mr. Trumpâs request.
He took undue credit for a new coal mine in Pennsylvania and the creation of 33,000 coal-mining jobs.
Corsa Coal Corporation held a grand opening for a new coal mine in southeastern Pennsylvania in early June, but the plans for the mine precede Mr. Trumpâs election by months. The company made its decision in August 2016 and showcased the project to investors in October.
He repeated inaccurate claims about the Paris agreement.
Mr. Trump misleadingly pointed to Chinaâs compliance pledge to argue that the climate deal âputs us at a permanent economic disadvantage.â
Though China says it expects emissions to peak by 2030, that doesnât mean the country is planning to ignore the pledge until then nor can it meet its goal overnight in 2029. It is already on track to beat that target and also pledged to get 20 percent of energy from non-fossil-fuel sources by 2030.
And despite Mr. Trumpâs protest âlike hell itâs nonbinding,â there are no serious legal restraints or penalties for falling short of declared targets in the deal.
He exaggerated his actions toward Cuba as âcanceling the prior administrationâs completely one-sided deal.â
The new directive prohibits self-directed trips to Cuba and business transactions with firms controlled by the Cuban military, but many Obama-era policies were unaltered. Embassies in Washington and Havana will remain open, commercial planes will keep flying between the two countries, and Cuban-Americans can still send money and visit family in Cuba. Mr. Trump also declined to restore an immigration policy eliminated by Mr. Obama that allowed Cubans come to the United States without a visa to remain.
He said he would bar immigrants from receiving welfare benefits for five years, but they already are prohibited.
The requirements sought by Mr. Trump have largely been in place for two decades since the passage of welfare reform or the Personal Responsibility and Work Opportunity Reconciliation Act of 1996.
Legal permanent residents who havenât worked in the United States for 10 years are not eligible for food assistance or Medicaid within the first five years of entering the country. States have the option of waiving the Medicaid rule for pregnant immigrants and children.
Refugees, asylees and victims of trafficking can collect some benefits, and immigrants whoâve served in the military are eligible without a time requirement.
He prematurely touted âhundreds of billions of dollarsâ of deals made in Saudi Arabia.
This figure is puffed up. The United States offered Saudi Arabia defense capabilities valued at $110 million, a fifth of which occurred under the Obama administration. It also remains to be seen how much the kingdom will purchase. Several U.S. companies also announced commercial deals, but the vast majority of these announcements were memorandums of understanding or letters of intent â not finalized, formal business contracts.
