In an exchange over immigration, Mitt Romney tried to return to a previous charge by President Barack Obama about his investments in Chinese companies, which make surveillance equipment that allow the communist government to spy on dissidents.
"Any investments I have over the last eight years have been managed by a blind trust and I understand they do include investments outside of the United States, including Chinese companies," said Romney, who criticized Sen. Ted Kennedy's blind trust as an age-old ruse in the 1994 Senate race.
"Mr. President have you looked at your pension?"
"Have you looked at your pension?" Romney said, turning to Obama and walking toward him.
"I don't look at my pension. It's not as big as yours, so it doesn't take as long," Obama said to laughter.
"Let me give you some advice," said Romney. "Let me give you some advice: You also have investments in Chinese companies, you also have investments outside of the United States. You also have investments in a Cayman trust."
Obama then turned the discussion turned back to immigration.
