Lawmakers in both houses of Congress filed legislation on Tuesday that would formally designate the Muslim Brotherhood a sanctioned terrorist organization, according to an advance copy of the legislation obtained by the Washington Free Beacon.

The legislation outlines the Brotherhood’s long history of sponsoring terrorism and outlines congressional support for it to be designated a global terrorist outfit. The bill also would force Secretary of State John Kerry to explain why the Obama administration has been hesitant to label the Brotherhood a terrorist group.

The Brotherhood’s political wing has been banned in Egypt, where affiliates of the organization overthrew the government and then violently cracked down on its opposition, the United States has avoided labeling the organization a sponsor of terrorism.

Should the State Department refuse to move forward with the designation, the bill would require it to provide a justification for this policy, according to the bill.

Multiple House lawmakers spearheaded a similar effort last year, but the bill failed to become law.
