Washington DC - President Donald Trump on Wednesday floated ending federal disaster relief and leaving states to fend for themselves during emergencies in his first Oval Office interview since returning to power.

With Los Angeles scorched by wildfires and the eastern US still recovering from two devastating hurricanes, Trump falsely accused the Federal Emergency Management Agency (FEMA) of turning its back on victims.

"FEMA has not done their job for the last four years. You know, I had FEMA working really well. We had hurricanes in Florida, we had Alabama tornados," Trump told Fox News.

"But unless you have certain types of leadership, it gets in the way. And FEMA is going to be a whole big discussion very shortly, because I'd rather see the states take care of their own problems."

Trump's remarks came as an explosive new wildfire erupted north of Los Angeles, forcing tens of thousands of people to evacuate their homes and setting nerves jangling in an area still reeling from two deadly blazes.

Trump and Republicans in Congress have said that help for California should be conditioned on the actions of the state's Democratic leaders, whom he has blamed for the fires.

Trump's freewheeling press conferences and interviews distinguish him from Joe Biden, who almost never agreed to sit down for detailed conversations with journalists.

The Republican during his campaign embraced podcasts, YouTube, and other new media, but he went with tradition for the pre-taped primetime appearance, sitting down with Fox News star and staunch loyalist Sean Hannity.

Trump, who has more than a dozen ex-Fox News employees in his administration, discussed his barrage of executive orders and his plans for the first 100 days – the third day in a row he has spoken directly to the press.

The TV viewing figures for Trump's second inauguration were significantly lower than in previous years, with a peak of 34.4 million people tuning in, according to The New York Times – four million down from his first inaugural speech.

Hannity – an unapologetic mouthpiece for Republican talking points who became known as Trump's "unofficial chief of staff" – has the highest rated cable show for the 9:00 PM hour, pulling in an average of 2.8 million viewers.

In the interview, Trump again defended his blanket pardons for hundreds of violent criminals who stormed the Capitol in 2021, dismissed security concerns over Chinese-owned app TikTok, and discussed the possibility of cutting off federal funds to so-called "sanctuary cities" that shield undocumented migrants from federal detention requests.
