Mentioning that he worked with Manchin on the passing of the American Rescue Plan earlier this year, Sanders said he was hopeful the Senate would pass the $3.5 trillion spending bill package. 

Manchin said on Sunday that he would not support the $3.5 trillion package, which the Senate hopes to pass this week so the House can pass the measure by Sept. 27. 

Manchin proposed a $1 trillion to $1.5 trillion spending package that will address child nutrition, unemployment and the tax code.
