JPMorgan Chase & Company is coming under fire for the way it conducted an online contest to award millions of dollars to 100 charities.

At least three nonprofit groups — Students for Sensible Drug Policy, the Marijuana Policy Project and an anti-abortion group, Justice for All— say they believe that Chase disqualified them over concerns about associating its name with their missions.

The groups say that until Chase made changes to the contest, they appeared to be among the top 100 vote-getters.

“They never gave us any indication that there was any problem with our organization qualifying,” said Micah Daigle, executive director of Students for Sensible Drug Policy. “Now they’re completely stonewalling me.”
