Donald Trump is back and after his inauguration it was down to business. 

One of his first acts was to pardon more than 1,500 defendants from the attack on the Capitol on January 6, 2021.

He also withdrew the US from the Paris climate accord and the World Health Organisation.

Donald Trump has brought the social media app TikTok back to life in the United States after an outage lasting less than 24 hours. 

The platform run by Chinese-owned ByteDance went offline for US users, with the firm saying it acted to comply with a law that banned it unless it sold its US operations to local owners. 

The law was passed with US politicians citing national security concerns. 

But it only took a promise from the incoming president to sign an executive order delaying the ban to get content creators and scrollers back online. 

Today, Vittoria Elliott from WIRED on why the TikTok ban failed and what happens next.

After months of talks a deal has been done for a ceasefire in Gaza, with it set to start on the weekend with the first phase to include the release of some Israeli hostages.  

Incoming US president Donald Trump has taken credit for it and his impending inauguration did give the negotiations a boost.

Today, Hussein Ibish from the Arab Gulf States Institute on whether peace will hold.

He says there's enormous relief felt on both sides, with Israelis overjoyed at the prospect of getting hostages back and Palestinians desperate for a break from the violence. 

He highlights the significant pressure placed on Prime Minister Netanyahu by Trump to finalise the deal before his inauguration. 

Dr. Ibish also discusses the complexities of the agreement, including the phased approach and the challenges of ensuring a lasting peace. 

He notes the potential for renewed conflict if key actors are not fully committed to the ceasefire.

The Australian dollar is at its lowest level against the US dollar in five years. 

That hurts travellers going to the United States for a holiday, but some economic commentators think it also means Australia’s Reserve Bank should hold off longer on cutting interest rates. 

Our chief business correspondent Ian Verrender doesn’t agree. 

Today, he explains why China and Trump are largely behind the fall in the Australian dollar and why interest rate cuts should still be on the table. 

Ian says the strength of the US dollar, driven by Trump's tariffs and economic policies, is a major factor in the Australian dollar's decline.

In 2024, voters in more than 60 countries went to the polls in what’s believed to be the biggest year for elections in history. 

This year it’s Australia’s turn and if we follow the voting trends of other nations, we’ll either kick Anthony Albanese’s Labor party out of office or come close to it. 

That’s because there’s a big movement, particularly in western democracies against incumbent governments.

Today, Mark Kenny from the Australian Studies Institute at the Australian National University explains the major shift in voting patterns. 

He highlights how the post-pandemic economic struggles and rising distrust in democratic institutions are driving voters to seek change.

Mark Kenny warns of the potential long-term implications for democratic stability if current trends continue. 

He says a lot of voters feel betrayed by their governments and there is a factual basis to the sense of umbrage felt by citizens towards their governments.
