Trump tries to dominate at the UN as his approval ratings plummet and even some Republicans stray from the script

Donald Trump stood before the United Nations on Tuesday and threatened to “annihilate” Iran. Yet even as the most powerful man on the planet flexed his military muscles, he was powerless to keep the gravitational pull of domestic politics at bay.

Heading into the UN building in New York, the US president was questioned by Kaitlan Collins, an anchor at CNN, which he had banned from the White House before a judge ruled against him. “I’m surprised that CNN is here covering me,” the 80-year-old snapped. “You should not be here covering me.”

The lashing-out was a reminder that even Trump, who has expanded executive power and dominated the national consciousness, finds some things beyond his control. Indeed, 20 months into his second term, there is a widening gap between the president’s self-perceived invincibility and the reality of his waning influence.

Federal courts are reining him in. Congressional Republicans are straying from the script. Poll numbers are tumbling to historic depths, driven by persistent inflation, rising fuel costs and an increasingly unpopular war in Iran. For the first time since his improbable political resurrection, Trump’s aura of authority is fading.
