As parliamentarians in Baghdad work to form a new governing coalition in the wake of this month’s elections, their counterparts in Washington are seeking to sanction more than a dozen of the Iraqi legislators over their links to Iran.

The House of Representatives unanimously voted last week on legislation requiring President Donald Trump to sanction “persons that are officials, agents, affiliates of or owned and controlled by” two prominent Iran-backed militias that operate in Iraq and Syria. The amendment from Rep. Ted Poe, R-Texas, to a must-pass annual defense authorization bill targets Asaib Ahl al-Haq and Harakat Hezbollah al-Nujaba, both of which are part of the Shiite-led Popular Mobilization Units battling the Islamic State.

Both militias joined with other Iran-backed military forces as part of the Fatah, or Conquest, political coalition, which came in second in the May 12 elections with 47 out of 329 parliamentary seats. Asaib Ahl al-Haq won 14 of those 47 seats, according to Iraq analyst Kirk Sowell, while Harakat Hezbollah al-Nujaba did not field any candidates.

“The US Department of Treasury will ultimately determine if the political wing constitutes an affiliate or entity controlled by” Asaib Ahl al-Haq, a Poe aide told Al-Monitor. “Congressman Poe believes [Asaib Ahl al-Haq] will likely be subject to these penalties unless it completely breaks all ties with the armed wing, renounces violence and acts solely as [an] Iraqi political party with no backing from Iran.”
