Donald Trump's trial has started in New York.  

It's the first time a US president has faced a criminal trial.  

Trump is charged with falsifying business records over his alleged role in a hush money scheme before the 2016 election.  

He's pleaded not guilty.  

The trial is one of four criminal cases he faces and may be the only one to face a jury before the election.  

Former adviser to George W Bush, Scott Jennings, told Mike Hosking that the chances of him being convicted in New York City are pretty high.  

But, he says, the issue itself is of low concern to Americans, the bigger issue would be if they get to trial for charges he faces about January 6.
