The first big pushback to Donald Trump’s "Liberation Day" tariffs has come from China, which has slapped its own reciprocal tariff on the US, at a rate of 34%, matching the figure the president set.  
 
On Day 76, US correspondents Mark Stone and Martha Kelner discuss how China's strike back has been received in the US, and how this could signal the start of a global trade war.  
 
Plus, Martha has been on the road following the impact of the president’s deportation agenda and investigating the case of one of more than 200 men deported to an El Salvador mega-prison.
