Watch Live: Biden addresses U.N. General Assembly

President Biden is set to address the United Nations General Assembly in New York for the second time as president on Wednesday, when he will announce new U.S. investments to address global food insecurity, rebuke Russia over the war in Ukraine and tout his administration's foreign policy actions since he took office.

The address comes as Mr. Biden seeks to rally global leaders to continue supporting the Ukrainian government with arms and financial aid, with the war now in its seventh month. Mr. Biden will emphasize the principle of the United Nations charter that countries cannot conquer their neighbors by force, national security adviser Jake Sullivan told reporters Tuesday. 

Now "is a moment to stand behind the foundational principles of the charter," Sullivan said during Tuesday's White House press briefing.
