Obama was asked about Neda during his news conference on Tuesday. He said he has seen the footage, which in many ways has become the visual image of the post election protests in Iran.
"It's heartbreaking," Obama said. "It's, uh, It's heartbreaking."

"I have concern about how peaceful demonstrators and people who want their votes counted may be stifled from expressing those concerns," Obama said.
