The donor group is made up mostly of Canadian Muslim professionals, such as lawyers and doctors. Formed in December 2014, the group helped Justin Trudeau to his first election victory in 2015.

The group says it has directed hundreds of thousands of dollars to the Liberal Party annually since December 2014. One member of the group — whose donation records CBC News verified with Elections Canada — has contributed nearly $19,000 to the Liberals since the group's foundation.
