Not backing down, says Trump amid calls to pull back tariffs proposal

US President Donald Trump faced growing pressure on Monday from political and diplomatic allies as well as US companies urging him to pull back from proposed steel and aluminium tariffs, although he said he would stick to his guns.
Inside the White House, there still appeared to be confusion about the timing and extent of the planned tariffs, which would hit allies like Canada and Mexico hard.

Efforts by Trump and US trade negotiators to link the NAFTA trade pact talks to the duties received short shrift from Ottawa and Mexico City.

Leading Republicans turned up the pressure on Trump, with House of Representatives Speaker Paul Ryan leading the charge. Ryan's home state of Wisconsin would be hit by proposed European counter-measures on Harley-Davidson Inc motorbikes.
