At UN, Trump to face questions about Iran, Ukraine, allies

President Donald Trump heads into a three-day visit to the United Nations this week hoping to lean on strained alliances while fending off questions about whether he sought foreign help to damage a political rival.

NEW YORK -- President Donald Trump heads into his three-day visit to the United Nations this week hoping to lean on strained alliances while fending off questions about whether he sought foreign help to damage a political rival.

Trump's latest U.N. trip comes after nearly three years of an "America First" foreign policy that has unsettled allies and shredded multinational pacts.

A centerpiece of this year's U.N. schedule will be a Monday session on climate change that Trump plans to skip.

Instead, he will address a meeting about the persecution of religious minorities, particularly Christians, an issue that resonates with Trump's evangelical supporters.
