The Task Force to Investigate Terrorism Financing of the House Financial Services Committee released a report Tuesday highlighting the methods terrorist groups use to secure money and prescribing ways for the United States to combat them.

The report, which was the product of a bipartisan group created by Financial Services Committee chairman Jeb Hensarling in March last year, suggests that much work remains to combat terror financing despite many advances in preventing terrorists from acquiring the funding necessary to commit attacks in the post-9/11 era. To illustrate the seriousness of the national security challenge stemming from taking on terror finance, the task force specifically details the manner in which major terrorist groups have secured funding for their activities.
