Wall Street ends lower on Turkish Lira concerns

US stock indices closed the first session of the week lower on concerns over the collapsing Turkish Lira, which could pave the way for a financial crisis in the country with contagious effects in other nations, especially with emerging economies. 

Otherwise, US President Donald Trump warned Canada in another tweet while lauding Mexico by saying: "Deal with Mexico is coming along nicely. Autoworkers and farmers must be taken care of or there will be no deal. New President of Mexico has been an absolute gentleman. Canada must wait. Their Tariffs and Trade Barriers are far too high. Will tax cars if we can’t make a deal!".

Trump has repeatedly blasted the NAFTA trade deal with Mexico and Canada, describing it as the worst in US history and blaming it for harming US farmers and workers.
