Legislation to regulate the sale of non-human primates, to create an independent revenue stream for the Washington-area Metro system and to expand paralysis research are among roughly three dozen bills combined into a single package that Senate Majority Leader Harry Reid introduced Tuesday. .

The roughly 400-page measure is an amalgamation of unrelated, narrowly tailored bills, most of which have been blocked by objections from conservative Tom Coburn, R-Okla.

The proposal by Reid, D-Nev., would authorize $11.3 billion in federal spending and would create more than 34 new federal programs, according to an analysis prepared by Coburn’s staff.

Coburn has used an informal Senate practice known as a “hold” to stall action on roughly 80 bills, refusing to allow the measures to pass without first dedicating floor time to debating and possibly amending them.

Democratic leaders decided to roll some of those bills into a package, betting that the bipartisan support many of the measures enjoy will tempt Coburn’s fellow GOP senators to split with him and support the package. The Senate is expected to consider the proposal later this week, and Reid could force a weekend session to advance the package if Coburn refuses to relent.

Coburn, meanwhile, contends that the proposal represents misplaced priorities, placing senators’ parochial wishes above important national issues.

“It reads like an election-year wish list,” said Coburn spokesman John Hart.

Coburn’s holds could be overcome with cloture votes on the new package, but that would require GOP support to reach the 60 votes needed to break a filibuster. It is unclear whether GOP senators will back Coburn or join Democrats in voting to advance the package.
