Carl Levin actually said...

"I think we need to worry less about the fragmentation of the market than we do about the fragmentation of regulation."

"That is why the market centers have proliferated to the extent that they have since Regulation NMS went into effect in 2007."

"The very markets we rely on to jump start our economy and invest in America's future are susceptible to market dysfunctions that jeopardize investor confidence."

"In my judgment, since these markets are so connected, it would seem to me that there is nothing preventing somebody from using one market to manipulate another market."
