"Why Manchin has concerns with including child tax credit in BBB, per source familiar - It has to do with how it impacts cost of bill, which he wants to keep at $1.75T - Manchin’s belief is that if the CTC is expanded over 10 years it would blow up the cost of the bill."
"- He isn't telling Biden to remove any specific policy, according to the source, but he has made clear that these expensive provisions are not going to fit to keep the bill at $1.75T -- Biden's framework would extend CTC for ONE year."
