Here's your Forbes Daily Briefing for Tuesday, April 29th.

Today on Forbes, 10 Shark Tank companies caught on the front lines of Trump's trade war.

Donnie McCall drove into Shark Tank in 2012 with a pickup truck and a dream.

He wanted $100,000 for 10% of Envisarack, a collapsible cargo rack aimed at

tradespeople. The sharks liked what they saw, but hated the high production costs that came

McCall said his revenue was about $50,000 in the first year,

at a landed cost of $250 per unit. Kevin O'Leary pushed McCall to move manufacturing overseas,

saying it would cut expenses nearly in half and open the doors for working with distributors.

O'Leary suggested, quote, let's just say that a

McCall didn't budge. He was committed to creating jobs in the U.S. and believed customers would

pay more for American-made quality. The sharks weren't convinced.

None made an offer.

Barbara Corcoran said McCall was too resistant and close-minded to be a good partner.

O'Leary told him he wasn't willing to do what it takes.

Robert Hergevac, whose father worked in a factory, said he respected McCall's values,

but couldn't back a business that ignored global realities.

Even Mark Cuban, who admired the mission, said the numbers just didn't work without going offshore.

For years, the sharks, just like most private equity firms, advised entrepreneurs to move manufacturing overseas to save money.

Lower costs overseas boosted profits and gave consumers cheaper goods.
