On Tuesday, President Trump is going to address the United Nations General Assembly for first time since taking office.
The White House says the speech,
"Frames his foreign policy in rational terms for a global audience."
Some speculate the president may use the world stage to announce the U.S. is getting out of the Iran Nuclear Deal.
The president is also expected to be tough on North Korea. He led a discussion on Monday about UN reform to a smaller group,
"We encourage all member states to look at ways to take bold stands at the United Nations toward changing business as usual."
After his speech Tuesday, the president has a full day of meetings. He'll meet with more than a dozen leaders by the end of the week.
