JOE BIDEN: On Saturday, at my direction, the United States successfully concluded an airstrike in Kabul, Afghanistan, that killed the emir of al-Qaida, Ayman al-Zawahiri. You know, Zawahiri was bin Laden's leader. He was with him all the whole time. He was his number two man, his deputy at the time of the terrorist attack of 9/11. He was deeply involved in the planning of 9/11, one of the most responsible for the attacks that murdered 2,977 people on American soil.

For decades, he was the mastermind behind attacks against Americans, including the bombing of the USS Cole in 2000, which killed 17 American sailors and wounded dozens more. He played a key role, a key role, in the bombing of the US embassies in Kenya and Tanzania, killing 224 and wounding over 4,500 others.

He carved a trail of murder and violence against American citizens, American service members, American diplomats, and American interest. And since the United States delivered justice to bin Laden 11 years ago, Zawahiri has been a leader of al-Qaeda, the leader. From hiding, he coordinated Al Qaeda's branches and-- all around the world, including setting priorities for providing operational guidance that called for and inspired attacks against US targets.

He made videos, including in recent weeks, calling for his followers to attack the United States and our allies. Now justice has been delivered, and this terrorist leader is no more. People around the world no longer need to fear the vicious and determined killer.
