HP Inc. joins Coca-Cola and Microsoft in deciding to either significantly curtail or eliminate its monetary support to the Republican convention.

Coca-Cola has declined to match the $660,000 it gave for the 2012 Republican convention, donating only $75,000 for this year and indicating that it does not plan to provide more.

Microsoft will provide only software and technical assistance to the Republicans’ event, while it plans to give that and monetary support to Democrats.

Political conventions and the cities that host them rely tremendously on corporate donations to fund their expenses, which can exceed $100 million when security costs are included. But companies have been wary of committing to the Republican National Convention this year given Mr. Trump’s provocative and offensive statements on women and minorities.
