The FBI has launched multiple investigations into individuals affiliated with Hamas following their attack on Israel last month. The attack set off a "March for Israel" on the National Mall, and FBI Director Christopher Wray is set to testify before the House Homeland Security Committee on Wednesday to discuss the elevated terrorism threat and the "rogue's gallery of foreign terrorist organizations" identified since the attack. Wray's testimony will provide more insight into the FBI's efforts to combat terrorism and protect Americans from potential attacks.
