The Senate voted unanimously on Wednesday to reject a $3.7 trillion budget plan that President Obama sent to Capitol Hill in February.
Ninety-seven senators voted against a motion to take it up.
Democratic aides said ahead of the vote that the Democratic caucus would not support the plan because it has been supplanted by the deficit-reduction plan Obama outlined at a speech at George Washington University in April.
McConnell said Obama’s budget “continues the unsustainable status quo.”
He noted during a floor speech Wednesday that Democrats initially applauded the plan.
The president’s budget called for ending tax cuts for the wealthy and a three-year domestic spending freeze, saving an estimated $1.1 trillion over 10 years. Democratic senators at the time called it “an important step forward”, “a good start” and a “credible blueprint.”
No Democratic senator was willing to support it, however, after Obama discussed a more ambitious plan at George Washington University to save $4 trillion over 12 years. Republicans criticized his speech for lacking detail.
The White House Office of Management and Budget declined to comment on the president's budget receiving zero votes in the Senate.
