Trump publicly attacked Democratic Congressman Ro Khanna for his economic message on Fox News, which Khanna says proves left-wing populism on manufacturing is the path back to power for Democrats.

• Khanna toured factory towns in Pennsylvania, Ohio, and Michigan attacking Trump for allowing Chinese steel imports and failing to protect American manufacturing jobs.
• Trump responded with a string of insults, saying Fox News should not let Khanna on air because anchors cannot rebut his arguments.
• Khanna argues Trump's anger shows the issue Democrats should run on: economic populism aimed at working-class voters Trump won twice.
• He says most Democrats refuse to go on Fox News, which is why their message never reaches Trump voters.
• Trump claims credit for reviving steel through tariffs, but Khanna counters that tariffs alone cannot rebuild factories without real investment.

Outlook: Khanna is positioning himself as a leading voice for a Democratic pivot to economic populism heading into the next election cycle.
