Economist and Columbia University Professor Jeffrey Sachs slammed the government for refusing to explain the details behind the assassination attempt against Donald Trump.

Speaking to Tucker Carlson, Sachs said that the lack of background on what led to Trump being shot is what happens when the government refuses to level with citizens.

'We don't know what happened, it's absolutely shocking, we don't know the story and whether we ever will know the story is, like so many things now that are huge events,' he said. 

Sachs - an Ivy Leaguer who has worked with the UN in the past but has been on the outs with liberal elites since promoting the COVID-19 'lab leak' theory - blames Americans' short attention spans preventing them from keeping Washington accountable.

'Assassination attempt on Trump, isn't that weeks ago? That's old news, we don't even talk about that anymore! We have no attention span, we have complete lying from the government, we have secrecy and confidentiality, so we never solve any of these issues'.

He then went on to complain about the government's attitude toward its citizens in return.

'The thing that gets me about Washington is they don't feel they have to respond to anything and you watch the spokespeople... they smirk! Right in your face to tell you you are nothing! We can tell anything to you! They smirk!' 

Trump, 78, was shot at a Pennsylvania rally on July 13, with the bullet piercing the skin of his right ear. He says it was 'miracle' and act of God that he survived.

Last week, the FBI revealed that investigators who have conducted nearly 1,000 interviews do not yet have a motive for why 20-year-old Thomas Matthew Crooks shot at Trump during a July campaign rally.
