Sen. Marco Rubio (R-Fla.) has threatened to vote against the tax bill, putting the legislation in danger of being delayed past Christmas.
Rubio has told Senate leaders that he will vote against the bill unless the child tax credit is made more generous to help lower-income workers who pay payroll taxes and not regular income taxes.
"Right now it's only $1,100. It needs to be higher than that," Rubio said.
Does Rubio have the leverage now that every GOP vote counts in this must win legislation? Do you agree with his proposal?
