On March 30, U.S. President Trump threatened to close the U.S. border with Mexico within a week if Mexico doesn't "immediately" step up its efforts to block immigrants attempting to enter the U.S. illegally.
"If you can close down the border when you're mad at anything, what is the value of a deal?" he said.
The trading relationship between the USA and Mexico is so intricate that many grocers supplement their US produce with imports from Mexico throughout the year, depending on consumer demand, says Richard Owen, a vice president at Produce Marketing Association, which represents companies that supply fresh produce and flowers.
"Sure it's going to have a negative impact on the economy", he said. "So those two things are certainly helpful and we'd like to see them continue", Sanders said. "So if we get closer to Thursday or Friday and Wall Street starts to teeter, that's when you might really think this may actually happen", Blackburn-Dwyer said.
"There's a deep disconnect, or even a pathology of sorts, festering at the core of the Trump administration's response to the humanitarian crisis at the southern border", Plum Line columnist Greg Sargent wrote Wednesday.
Senior U.S. Department of Homeland Security (DHS) officials said Tuesday a redeployment of some 750 officers on the border to deal with a surge in migrants - mostly Central American families turning themselves into border agents - had led to a slowing of legal crossings and commerce at ports of entry.
"We're going to have a strong border or we're going to have a closed border", he told reporters as he met NATO's secretary general.
"Wait times in Brownsville [Texas] were around 180 minutes, which were two times the peaks of previous year", said a senior DHS official on a call with reporters.
But the fact that White House officials are looking at ways to address the fallout of his latest threat shows how real the option has become, at least internally. According to Dziczek, roughly 70 per cent of the wiring harnesses used in US -built vehicles come from Mexico.
The biggest priority for Nielsen is to seek action from Congress to change the immigration laws, said a DHS official.
Meanwhile, President Trump doubled down on his threat to close the U.S. -Mexico border in a recent tweet.
"Any action that stops commerce at the border would be harmful to the USA economy, and in particular, the auto industry". But Trump has so far refused to back down. U.S. companies imported $314.3 billion in goods from Mexico in 2017, according to the Office of the U.S. Trade Representative.
A typical vehicle is assembled from 30,000 parts and Mexico is the largest source of foreign components for USA manufacturers, who have geared their production to lean inventories and just-in-time delivery. She reportedly added that 900,000 people are coming to the USA this year "without any legal right to stay".
