Being an attorney is about service and trust.

Holding Iran Accountable for Hamas Terrorist Attacks
The world has watched in horror as tragedy has unfolded in Israel because of the brutal terrorist attacks carried out by Hamas. Nothing can compensate for the devastating loss of life, for the trauma suffered by those injured or kidnapped, or for the grief, sorrow, fear, and anger felt by family members. For the past twenty-five years, American victims or family members have held Iran accountable in U.S. courts for its sponsorship and support of murderous and terrorist acts like those carried out by Hamas in Israel. The U.S. legal system may again be a vehicle to hold Iran and its proxies to account today.
