At the peak of birtherism, you may remember, an Army lieutenant colonel refused to deploy to Afghanistan absent proof that President Obama was born in the United States. The officer, a doctor named Terrence Lakin, was court-martialed, found guilty, jailed, and discharged from the Army.
One of Donald Trump's introducers today at the new Trump Hotel, was a retired Air Force general who supported Lakin. He even submitted an affidavit on his behalf, questioning whether Obama was properly within the chain of command, since his U.S. birth was in question.
So there you have it: Trump brings a birther to his presser purporting to disavow birtherism.
