U.S. President Donald Trump’s top envoy to the EU told POLITICO that overregulation is causing “real problems” economically and forcing European startups to flee to America.

Andrew Puzder said businesses in the bloc “that become successful here go to the United States because the regulatory environment is killing them.”

“Wouldn’t it be great if this part of the world, instead of deciding it was going to be the world’s regulator, decided once again to be the world’s innovators?” he added in an interview at this year’s POLITICO 28 event. “You’ll be stronger in the world and you’ll be a much better trade partner and ally to the United States.”

Puzder’s remarks come as the Trump administration launched a series of blistering attacks on Europe in recent days.

Washington’s National Security Strategy warned of the continent’s “civilizational erasure” and Trump himself blasted European leaders as “weak” and misguided on migration policy in an interview with POLITICO.

Those broadsides have sparked concerns in Europe that Trump could seek to jettison the transatlantic relationship. But Puzder downplayed the strategy’s criticism and struck a more conciliatory note, saying the document was “more ‘make Europe great again’ than it was ‘let’s desert Europe’” and highlighted Europe’s potential as a partner.
