GOP senator: Trump budget chief could face confirmation 'problems'

Mick Mulvaney (R-S.C.) could face difficulty getting confirmed as a top financial analyst because of his failure to pay taxes on a household employee.  

"It could create problems," Grassley told CNN on Thursday. "I don't know for sure, but I've had problems with former Cabinet people under both Republicans and Democrats where that's either been straightened out — or if there wasn't justification for it oppose it."
Mulvaney, Trump's pick to lead the Office of Management and Budget, acknowledged in a committee questionnaire that he initially failed to pay roughly $15,000 in taxes on the employee. He said he has since paid the taxes, as well as related penalties. 
Grassley sits on the Budget Committee, which is holding a confirmation hearing for Mulvaney next week. The GOP senator stopped short of saying whether he thinks Mulvaney should withdraw his nomination, according to CNN. 
Democrats have seized on Mulvaney's failure to pay taxes, using it as an example that GOP senators are trying to rush through nominations without proper vetting. 

"Republicans insisted that that disqualify him from becoming HHS secretary. I’ll say to my Republican colleagues on the other side of the aisle," Schumer said. "What’s good for the goose is good for the gander." 

Democrats will need to flip at least three Republicans if they want to block Mulvaney. Republicans have a 52-seat majority and Trump's nominees will need only 50 votes to clear the Senate.

Rep. James Clyburn (S.C.), the No. 3 House Democrat, told reporters that he was giving Mulvaney the "benefit of the doubt."

"I hope, with him, it was an oversight," he said. "He is a South Carolinian, and I want to be proud of all South Carolinians."
