The Justice Department is forming a team of prosecutors to investigate drug trafficking and money laundering linked to Iranian-backed Hezbollah militant movement, Attorney General Jeff Sessions said Thursday.

The move follows reports that Obama administration officials thwarted drug prosecutions related to Hezbollah for fear of jeopardizing a nuclear deal with Iran.

President Donald Trump and congressional Republicans have been relentless in pressuring Sessions to take a fresh look at Obama-era dealings, in an effort that Democrats contend is aimed at steering attention away from investigations into Trump campaign ties to Russian election meddling.
