Nikki Haley says the U.S.  is not trying to foment revolution  there.

Security Council's Wednesday meeting on Iran, which  President Donald Trump will chair .  The Trump administration escalated tensions with Tehran when it pulled out of the Iran Nuclear Agreement in May and reimposed sanctions.

Since then, both countries  have accused each other  of backing proxies to  undermine stability in the region .

Trump's lawyer Rudy Giuliani said Saturday the U.S. would take advantage of the unrest economic sanctions have caused in Iran and  overthrow the government  there.

Haley contradicted those claims, saying the U.S. was "not looking to do regime change anywhere." Additional reporting by  Newsy affiliate CNN .
