Washington (CNN) - President Barack Obama's sister thinks the birther movement is "unfortunate."
"I think it's unfortunate. He was born in Hawaii, there is a tremendous amount of proof that has already been presented," Maya Soetoro-Ng told CNN's Piers Morgan in an interview scheduled to air Tuesday. "I think that it is time for people to put that to bed, put it to rest completely."
And what about real estate mogul Donald Trump's repeated calls for the president to produce his birth certificate?
"Well, I think it's a shame and I think that my brother should definitely be president for a second term," Soetoro-Ng said. "And that's really all I have to say about it."
Trump, star of "Celebrity Apprentice," has made a second career out of questioning the president's birthplace, most recently on CNN's "State of the Union."
In 2008, the Obama campaign released a copy of the certificate, saying the serial number was blacked out for concern over Hawaiian procedure. Since then, many news organizations and the Annenberg Fact Check Project saw the original with the serial number, an embossed seal and a stamped signature.
The comments from Obama's half sister followed similar remarks by his aunt Saturday.
In an interview with CNN affiliate WHDH Zeituni Onyango said Trump is "lying."
"He was born in Honolulu, Hawaii," Onyango said. "A naked lie in the name of the Lord."
"I respect his wealth, but I only demand him to respect us," Onyango added. "And I challenge him. Let him call me and we'll talk."
