Clinton, Sanders keep fighting over who is the minimum wage hero

They both agree the federal minimum raise should be raised, but Democratic presidential primary opponents Hillary Clinton and Bernie Sanders continued their fight over who is right about how to raise it Sunday morning.

Their debate within the debate over raising the minimum wage came down to $3 on ABC's This Week. Asked to respond about her support at the start of the campaign for raising the wage to about $12, Clinton noted that she has the overwhelming support of activists involved in the "Fight for $15" effort.

"Everyone wants to make this a big contrast," said Clinton, noting it is people "trying to make something were there is nothing."

If Congress were to pass a $15 federal minimum wage, "of course I'd sign it," said Clinton.

But she supports the New York plan to have a $15 minimum wage in cities, $12.50 upstate, rural areas and to continually evaluate the economic impact.

As for the $12 vs. $15 issue, Sanders said Clinton is "just not being accurate on that."

Furthermore, Sanders said he has the support of most of those holding the signs and that he has been "out in the rain" - with those participating in the "Fight for $15" demonstrations. That is proof, he said, that he wants to "lead that effort, not just follow."
