The White House said on Wednesday it strongly opposed a Republican-backed spending bill and said President Barack Obama will veto a bill if it undermines his priorities or national security or curtails drivers of long-term economic growth.

“The unbalanced bill would undermine the nation’s economic recovery and its ability to succeed in a complex global environment,” the White House said in a statement.

Showdown votes in the Senate will be held on both the House-passed Republican spending bill for the rest of this fiscal year, which ends Sept. 30, and a Democratic alternative. Neither measure is expected to get the 60 votes needed for passage.
