On Thursday night, Harris met with Israeli Prime Minister Benjamin Netanyahu and took the lead in addressing the public about their discussions.

You have always put this country ahead of yourself! We owe you an enormous debt of gratitude!" he said.
Shortly after the president delivered his remarks, massive applause and cheers were overheard pouring out of the White House, where hundreds of staff had gathered to watch their beloved boss deliver his historic address.
Biden sounded as if he were using a microphone to address his staff, starting with “Hello, hello, hello!” and being met with roaring applause.
At one point, it sounded as if the crowd broke into a chant of "Biden! Biden! Biden!"
