Now, after his exit last week, he is back on the outside. And it is the Trump administration – and the massive spending legislation the president is currently pushing – that is drawing the ire of this new, seemingly unshackled Musk.In a series of social media posts on Tuesday, he took aim at Trump's signature tax and spending bill that is being considered by the Senate after House Republicans passed it last month. After saying he couldn't "stand it anymore", Musk called the bill a "disgusting abomination"."Shame on those who voted for it," he said. "You know you did wrong."

And on Wednesday afternoon he went a step further, calling on voters to contact their representatives in Congress to voice their opposition. "Bankrupting America is not OK!" he wrote on X. "KILL the BILL."Musk's diatribe against the Trump-backed bill, which includes huge tax breaks and more investment in defence, comes after he spent months pushing for cuts to government spending.

In his posts, he said the legislation would add to the US budget deficit and saddle Americans with debt. He also warned Republicans who supported, or are planning to support, the bill that "we [will] fire all the politicians who betrayed the American people" in next year's midterm elections.

And it is that line that could be the most concerning for Republicans.An Australian woman on trial for murder says she threw up the toxic mushroom meal which killed her relatives, after binge-eating dessert.

Erin Patterson has pleaded not guilty to four charges - three of murder and one of attempted murder - over the beef Wellington lunch at her regional Victorian house in July 2023.Prosecutors allege Ms Patterson deliberately served toxic death cap mushrooms, but only to her guests. Her defence team say the contaminated meal was a tragic accident, and argue it had made their client sick too.

On her third day of testimony, Ms Patterson told the court she had only eaten a small part of the lunch and later consumed two-thirds of a cake, before vomiting.Ms Patterson also admitted she had lied about a cancer diagnosis - which prosecutors say she used to coax the guests to her house - as she was too embarrassed to tell them she was actually planning to undergo weight-loss surgery.
