Trump news – live: President returns to golf course while looming Hurricane Dorian sparks evacuation of one million people

Iran's information and IT minister Mohammad Javad Azari Jahromi has been teasing Trump on Twitter after the president posted a classified satellite photograph from his morning intelligence briefing late on Friday to deny US involvement in a mysterious explosion at the Imam Khomeini Space Center in the country.

With security experts marvelling at Trump's idiocy in publishing a secret graphic complete with annotations, speculation as to what caused the blast was rife, with the Nahid-1 satellite thought to have been the cause in some quarters.

Not so, says Jahromi.

Here's my report.

As the Trump administration continues to whip up tensions at the border, a protester was arrested in Oakland Park, Florida, on Friday for throwing a Molotov cocktail into the lobby of a US Citizenship and Immigration Services (USCIS) office.

Celia Hunt, 35, tossed a bottled filled with gasoline into the building but its fuse failed to ignite, meaning no one was hurt.

The incident follows a similar attack in August when a gunman fired on an Immigration and Customs Enforcement (ICE) office in San Antonio, Texas, from a car. There too, no one was injured.

Ken Cuccinelli, acting head of USCIS, responded on Twitter:

Here's the latest from the US-China trade war after both sides slapped extra tariffs on each other's goods in the wee hours of Sunday morning.

Trump is up and staring at an empty schedule.

After retweeting several Dorian updates from the National Hurricane Center, he is back to tweeting about whatever is on Fox News and attacking another New York Times columinst he takes exception to, this time Paul Krugman, followed by American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) chief Richard Trumka.

That last coming on Labor Day, no less.

More Comey-bashing via Fox. Has Dorian made landfall yet? 

Someone grab the remote, I'm begging you.

Fresh from covering for Trump in Poland, veep Mike Pence will arrive in Ireland later today for an official visit that will give him a chance to "reconnect with his Irish roots". Cue the memes. 

Put it this way, he can't do any worse than Eric Trump, who made a chump of himself utterly failing to pour a Guinness on a night out in Doonbeg earlier this summer.

This resurfaced video from Texas senator and former Republican presidential candidate Ted Cruz is absolutely insane and speaks volumes about America's toxic relationship with guns.

Here's our report.

Bearing in mind Sadiq Khan's comments about the president and white nationalism, here's Chris Riotta on efforts underway to deradicalise those to whom the hate movement appeals.
