A growing number of corporations are dropping or reducing their sponsorship of next month's Republican National Convention in Cleveland, according to a report by Bloomberg News.

The reasons involve the party's presumptive and controversial standard-bearer. Coca-Cola and Microsoft are among the companies who have already scaled back or dropped their support. Now Bloomberg reports Wells Fargo, United Parcel Service, Motorola, JPMorgan Chase, Ford, and Walgreens are ending their sponsorships. They sponsored the 2012 convention, but none are saying publicly why they are not backing this year's gathering. GOP operatives who advise companies on political activities tell Bloomberg the expected nomination of Donald Trump for president threatens the priorities of companies who support conventions to promote their brands and meet with state and federal officials. Bloomberg reports some top elected officials are skipping the convention this year, and there are threats of large-scale protests. And progressive activists say corporate sponsors are implicitly endorsing Trump’s controversial statements about Muslims, Mexican immigrants, and others. Former presidents George H.W. Bush and George W. Bush are among the top GOP names who have said they are skipping the Cleveland convention. The Cleveland host committee has said fundraising remains on track to reach its goal of 64 million dollars. Wells Fargo tells Bloomberg it will sponsor the Democratic National Convention in July.
