Republican senator: I am a no if GOP tax plan increases debt too much

Sen. James LankfordJames Paul LankfordA year into Trump's presidency, the media is still ignorant of his plan for a wall Trump's 's---hole' remark sparks bipartisan backlash GOP senator: Trump’s reported ‘s---hole’ comments ‘disappointing’ MORE (R-Okla.) said on Sunday that he would vote against the Republican tax-reform plan if it increases the debt too much. 

"I am a no. I want to make sure we have reasonable assumptions in the process for growth estimates," Lankford told NBC's Chuck Todd on "Meet the Press." 

"I’m actually not comfortable with increasing the debt. This is something that’s been a behind-the-scenes conversation for a long time. It’s one thing to be able to cut taxes, it’s another thing to be able to say, ‘how are we going to deal with our debt and deficit?’" he continued. 

Lankford's comments come after House Republicans introduced their tax-reform plan last week. It is expected to pass through the lower chamber, but face more opposition in the upper chamber. 

Debt watchdogs are not thrilled with the plan due to the fact it could add up to $1.5 trillion in debt over a decade.

"The reason we did it that way is because we believed that the Senate parliamentarian won’t let us use what we call dynamic scoring," Ryan said on "Fox News Sunday." 

"Let me just get you right there. You’re going to say this is a $1.5 trillion dollar tax cut — we are, we are convinced that this is going to give us faster economic growth. I’m not saying every tax cut pays for itself," he added.
