EXCLUSIVE — A progressive group linked to terrorism may have unlawfully failed to disclose lobbying, tax experts warn.

Alliance for Global Justice, an Arizona-based nonprofit group facing an uncertain future after a Washington Examiner investigation into its Palestinian terrorism ties prompted payment processors and donors to jump ship, claimed in recent years on financial disclosures filed with the IRS that the charity did not engage in lobbying activities. But records show AFGJ has lobbied on the state and federal level — a fact that went undisclosed and, thus, could place the group’s tax-exempt status in jeopardy and open it up to hefty fines.
