Republican McCain wavers on Trump's White House budget chief nominee
None
US Senator John McCain said on Wednesday he is leaning against voting to confirm US President Donald Trump's nominee to be White House budget director, Representative Mick Mulvaney.
A Senate vote on Mulvaney, a leading member of the conservative House Freedom Caucus who represents South Carolina, was expected on Thursday at 7 am (1200 GMT). Wavering support from McCain alone would not jeopardize Mulvaney's confirmation, but the Arizona senator and former presidential candidate could sway other Republicans. A Senate panel only narrowly backed the nominee earlier this month in a party-line vote.
Republicans have 52 of the 100 Senate seats and are able to approve Trump's nominees if they can hold together a majority.
