"From Sandy aid to tax reform @MickMulvaneyOMB tries to screw New York.
Probably feels inferior because New York subsidizes his state of South Carolina," King tweeted Tuesday evening.
King appeared to be reacting to comments Mulvaney made earlier in the day about the Republican tax reform plan, supported by the White House, making its way through the U.S. Congress.
"Is it the federal government's fault that New York taxes are so high that they're driving people out of the state?"
Mulvaney's comments Tuesday also elicited criticism from New York's Democratic side.
