US President Donald Trump's administration has proposed cutting funding to the State Department and the US Agency for International Development by more than a third in a move that drew immediate push-back from senators on both sides of the aisle.
The White House Office of Management and Budget has proposed cuts of 37 per cent at two agencies that provide US foreign aid, according to two people familiar with the matter who asked not to be identified because the figure hasn't been publicly disclosed. The State Department requested more than US$50 billion in its 2017 budget.
The cuts are part of Trump's plan to cut spending from the government's discretionary budget to fund increases in defence spending, according to Administration officials.
Some conservatives have objected to the way the State Department's programmes grew under President Barack Obama, with numerous special envoys and offices overseeing projects such as climate change and biodiversity.
"If it's anywhere in the ballpark of what I've seen about the State Department, that's definitely dead on arrival," Senator Lindsey Graham, a Republican from South Carolina, said of Trump's State Department cuts. "That guts soft power and puts our diplomats at risk."
Senator Bob Corker, the Tennessee Republican who heads the Foreign Relations Committee, said the budget process was only beginning. He said Secretary of State Rex Tillerson is in the process of preparing a response.
Asked if Congress would support such deep State Department cuts, Senate Majority Leader Mitch McConnell said: "Probably not".
Tillerson's own response wasn't immediately known, though he and Trump discussed the need to overhaul the department when he was interviewed for the job, according to a transition official familiar with the conversation.
"The department is working with the White House and OMB to review its budget priorities," acting State Department spokesman Mark Toner said. "The department remains committed to a U.S. foreign policy that advances the security and prosperity of the American people."
