WASHINGTON — MEK leader Maryam Rajavi told lawmakers on April 29 that the path to defeating the Islamic State (IS) runs through regime change in Tehran.

Testifying by teleconference from the exiled group's headquarters in Paris, Rajavi urged the United States to stand up to Iran throughout the region. Her appearance has sparked controversy because the MEK was listed as a terrorist group until 2012, but several lawmakers defended her right to testify and held up her organization as a viable democratic alternative to the mullahs.

"Since [1979], the regime in Tehran has acted as the driving force for, and the epicenter of, this ominous phenomenon regionally and worldwide," Rajavi testified before the House Foreign Affairs Committee's panel on Terrorism, Nonproliferation and Trade. "The ultimate solution to this problem is regime change by the Iranian people and resistance."

The hearing drew a crowd of MEK supporters, including a who's who of lawmakers who have long supported — and taken money from — the MEK and its Iranian-American affiliates. They include Reps. Judy Chu, D-Calif., and Sheila Jackson Lee, D-Texas, who aren't on the committee but stopped by to praise Rajavi.
