Detroit Mayor David Bing said Sunday that there is "not yet" a decision over a potential federal bailout for his city, which filed for bankruptcy last week.

Speaking on ABC's "This Week," Bing said he has engaged in talks with the Obama administration over potential options, but suggested both sides are still determining what the federal government can do to help.

“I’m not sure exactly what to ask for," Bing said. "I mean, money is going to help, no doubt about that. But how much? We have to have an organized plan so we know whatever we get is going to be an invested where we can maximize the return on investment.”

On Friday, Vice President Biden said the administration had not determined if and how it could help Detroit. "We don't know yet," Biden said after an immigration event, noting that administration aides were studying the matter.
