In February 2015, The Intercept published an investigative work by Ali Gharib and Eli Clifton, assisted in part by the work of independent researcher Joanne Stocker, indicating that Menendez has received at least two donations from the People's Mujahedin of Iran (MEK) before September 2012, when it was listed as a Foreign Terrorist Organization. Menendez became an outspoken advocate of the MEK after it was delisted, taking more than $25,000 between 2013 and 2015.[132]
