Donald Trump continues to motion at running for the 2012 Republican nomination, with a decidedly birther lean. He recently insisted during an interview that President Barack Obama’s birth announcements had ben planted so that Obama could one day enjoy the benefits of being American.

Last night on The Daily Show, Jon Stewart just couldn’t take it anymore.

“His mother was American, you fuckwad!” he burst out, running down the list of “crazy people” likely to make a bid for the GOP nod.

“What’s more likely? Obama was born here, or that his war hero grandfather conspired to plant false evidence in a Honolulu newspaper so his grandson could one day become a socialist overlord?”

Watch the clip below, which originally aired on Comedy Central’s The Daily Show with Jon Stewart on April 12, 2011.
