"Period." About 12 hours earlier, senior adviser Jason Miller said in a statement Trump had compelled Obama to release his birth certificate in 2011 to dispel questions about the fact he was born in Hawaii in 1961. "Mr. Trump believes that President Obama was born in the United States," the campaign conceded, a gesture meant to end questions -- which have bubbled up again in the past weeks -- surrounding Republican nominee's role in advancing a fiction meant to delegitimize the first African-American commander in chief.Trump himself has not publicly said he believes Obama was born in the USBut the Republican nominee used to have a lot to say about it
