who must approve the budget created by washington dc city council
Government of the District of Columbia The mayor and council set local taxes and a budget, which must be approved by the Congress.
United States budget process There is no obligation for either or both houses of Congress to pass a budget resolution. There may not be a resolution every year; if none is established, the previous year's resolution remains in force. For example, the Senate has not passed a budget resolution for FY2011, FY2012, or FY2013, and passed the FY2014 budget resolution on March 23, 2013, 23 days before the April 15 deadline set by the No Budget, No Pay Act of 2013. This was the first budget resolution passed by the Senate since a FY2010 budget passed on April 29, 2009. The House and Senate may propose a budget independently of the President's budget. For example, for the 2014 budget process, the House prepared its budget proposal on March 21 and the Senate proposed a budget on March 23, while the President's budget was not submitted until April 10.
