Sens. Bob Menendez, D-N.J. and Marco Rubio, R-Fla., introduced the resolution on the 25th anniversary of the attack on the AMIA Jewish center. The bombing in the Argentine capital left 85 people dead and hundreds more injured.

The perpetrators have still not been brought to justice. Argentina and Israel have long blamed Iran and implicated several former Iranian officials and Hezbollah in the attack, in addition to the March 17, 1992 attack on the Israeli Embassy in Buenos Aires that killed 29 and injured more than 200.

Menendez and Rubio were joined by four co-sponsors: Sens. Ben Cardin, D-Md.; Ted Cruz, R-Texas; Tim Kaine, D-Va.; and Todd Young, R-Ind.

“It is critical that the U.S. recommit to helping the Government of Argentina in their investigation,” Menendez said in a statement. “The Argentinian people have waited long enough for answers.”

Rubio added that the lawmakers were recommitting “to helping the Government of Argentina seek justice for the victims and their families.”
