Romney, a Republican presidential candidate, told a Boston talk radio host Wednesday Onyango Obama, who was arrested Aug. 24 in Framingham, Mass., and charged with drunken driving, should be deported, ABC News reported.
Onyango Obama is the half-brother of the president's late Kenyan father.
Romney was asked by Boston radio personality Howie Carr whether Onyango Obama should be deported.
"Well, if the laws of the United States say he should be deported -- and I presume they do -- then, of course, we should follow those laws," Romney said. "And the answer is 'yes.'"
When Carr brought up the case, using Onyango Obama's nickname "Omar," Romney had asked, "Who is Uncle Omar, Howie?"
At the police station after his arrest, a police report said, Onyango Obama told an officer, "I think I will call the White House."
