() President Donald Trump insists his tariffs will bring manufacturing jobs back to the United States, but the list of skeptics who doubt that will happen is growing longer each day.

Andrew Yang, an entrepreneur and founder of the Forward Party, said companies would need a “time machine” for Trump’s tariffs to make sense.

“If you could go back in time and have tariffs that protect these manufacturing facilities, you might have a case, but you can’t just conjure them up,” Yang told ‘s Chris Cuomo on Tuesday.

Rather than bring jobs back to America, Yang worries that Trump’s escalating trade war could have the opposite effect.

“Instead of reshoring manufacturing, [CEOs] are just cutting investment, they’re laying people off,” he said.

Yang, who ran for president back in 2020, pointed out that the real risk might be the uncertainty around Trump’s tariffs, not just the tariffs themselves.

“Does anyone have confidence that these tariffs are going to come in and stay at this level for six years? These CEOs don’t,” he said.

The entrepreneur turned politician said he thinks companies will invest in the U.S. but only if it’s a “winning economic proposition,” adding that tariffs aren’t going to do the trick.
