Mulvaney, a member of the Tea Party Caucus in the House of Representatives, has voted for spending cuts to balance the federal budget as well as for rollbacks of environmental rules meant to combat climate change and of the Dodd-Frank Wall Street Reform and Consumer Protection Act.
Powerful Appropriations Committee Chairman Thad Cochran of MS is also unwilling to commit to supporting Mulvaney in Thursday's up-or-down vote. He should easily clear a procedural tally, but Maine Republican Susan Collins says she'll oppose him on a subsequent confirmation vote. Cochran met with Mulvaney on Tuesday. John McCain, R-Ariz., said he was considering breaking party lines and voting against Mulvaney's confirmation.
Republicans had little margin of error in achieving Mulvaney's endorsement as they have 52 seats in the Senate and John McCain had already announced that he would vote against US President Donald TrumpÂ´s candidate.More news: Century mark: No. 1 UConn wins staggering 100th straight game
Sen. Tim Scott, R-S.C., said in a statement that Mulvaney "is an excellent leader and someone who has consistently represented conservative principles, especially when it comes to our budget".
Additionally, it wound up costing USA taxpayers "billions" in new investment to fix the problem caused by military withdrawals from Europe that McCain said Mulvaney supported "in the name of spending money".

"Congressman Mulvaney's beliefs, as revealed by his poor record on defense spending, are fundamentally at odds with President Trump's commitment to rebuild our military", said McCain on the Senate floor.
Trump has said that strengthening the military is more important than balancing the budget and is committed to ending budget caps.More news: Boy dies after Topshop incident
