Rep. Frank Wolf (R-Va.) has endorsed the “Gang of Six” spending deal and called for a House vote on the package, backing the work of Sen. Mark Warner (D-Va.) but breaking from many of his fellow House Republicans.

In a letter to Speaker John Boehner (R-Ohio), Wolf and Rep. Jim Cooper (Tenn.) — a leading Democratic moderate — wrote that the compromise negotiated by Warner and five senate colleagues “deserves the full and immediate attention” of the House.

“The Gang of Six is bitter medicine and, while not perfect, could restore our fiscal health,” they wrote. “There is never a convenient time to make tough decisions, but the longer we put off fixing the problem, the worse the medicine will be.”

The gang’s proposal, which includes a mix of spending cuts, revenue increases and entitlement reforms, has drawn some praise from the White House and the Senate but has so far earned a tepid response from many House Republicans. Wolf has long been an advocate for fiscal discipline, warning that the nation was on an unsustainable path and urging Congress to make needed reforms.
