When Donald J. Trump strides onto the inaugural ballroom floor this week amid the sprawling celebration of his swearing-in, he will have corporate America and many of its titans to thank for the rapturous greeting.
Chevron, the oil giant, has given $500,000 for the dayslong festivities. Boeing, which has been a target of Mr. Trump, pledged $1 million. And Sheldon and Miriam Adelson, giants of the gambling industry, are said to have donated more than that by themselves.
They are far from alone.
