Donald Trump’s attacks on a “global power structure” don’t add up because he spent his adult life trying to join that group, President Barack Obama said Friday.

At a rally in West Palm Beach, Florida, on Thursday, Trump railed against a group he said “is responsible for the economic decisions that have robbed our working class, stripped our country of its wealth and put that money into the pockets of a handful of large corporations and political entities.”

“The political establishment that is trying to stop us is the same group responsible for our disastrous trade deals, massive illegal immigration, and economic and foreign policies that have bled our country dry,” Trump said to applause.

“The political establishment has brought about the destruction of our factories, and our jobs, as they flee to Mexico, China and other countries all around the world. Our just-announced job numbers are anemic,” the billionaire businessman added.

Obama had a succinct response during a rally for Democratic nominee Hillary Clinton in Cleveland: “C’mon, man.”

For decades, “all he had time for is celebrities,” Obama said of Trump. “And now suddenly, he’s acting like a populist?”

And of the GOP nominee’s claims that he will be a champion for working people, Obama had a similar reaction: “C’mon, man.”

Obama also drew a straight line from congressional Republicans to Trump, saying their messaging campaign sowed the seeds of “conspiracy” theories that allowed Trump to build his campaign message and strategy.

“Donald Trump didn’t build all this crazy conspiracy stuff,” he said. “Some Republicans who knew better stood by silently.”
