Senate GOP anger at Reid boiling over

Senate Republicans on Thursday, angered after Majority Leader Harry ReidHarry ReidDraft House bill ignites new Yucca Mountain fight Week ahead: House to revive Yucca Mountain fight Warren builds her brand with 2020 down the road MORE (D-Nev.) blocked amendment votes on a bill, threatened to torpedo legislation they support on extending tax breaks.  

If Republicans follow through, it would be the second time this week that a bipartisan bill was stopped in its tracks because of a broader fight over Senate floor procedure.

Reid has refused to allow amendments on a bill that hit the chamber floor that would revive more than 50 tax breaks, commonly known as "extenders," that lapsed at the end of 2013.

"The time to negotiate amendments is before cloture is invoked," McConnell said on the Senate floor. "But I appreciate that the Senate Finance Committee chairman is moving in the right direction.

“We want to have amendments before cloture is invoked,” the minority leader added.

Even Hatch told reporters on Thursday that he was leaning toward voting to block the bill on Thursday.

“It’s more important to assert our rights than to do anything else,” said Hatch, the top Republican on the Finance Committee. “I consider the way the Senate is being run right now to be an absolute tragedy. It’s inexcusable.”

Republicans had been pushing an amendment to repeal the medical device tax in the Affordable Care Act, an idea that has received broad bipartisan support in a nonbinding vote last year.

But now they are threatening to scuttle the tax bill amid a long-running fight with Reid over Senate operations.

Most Republicans also voted to block an energy efficiency measure earlier this week, after the bill from Sens.

Lawmakers and lobbyists had thought the extenders package might have a better shot of pushing through the Senate, because it contained pet provisions for many senators.

The $85 billion package would extend the popular research credit for business, a popular tax credit for the wind industry and tax breaks for teachers and commuters through 2015.

Along with those, other tax breaks derided by critics as corporate pork, including incentives for NASCAR track owners and Puerto Rican rum distillers, would be revived by the legislation.

Reid has countered that it’s Republicans who are gumming up the works in the Senate.

“This useless, mind-boggling obstruction is what continually grinds the wheels of the Senate to a halt,” he said earlier this week during the energy efficiency debate.

“It’s a pro-business package. It’s a pro-people package, too,” Schumer said. “It’s hard to figure.”

Conservative groups like the Club for Growth and Heritage Action, though, have come out against the Senate plan, charging that many of the tax breaks benefit special interests.

Schumer added that Senate Democrats wouldn’t embrace the House GOP approach to the expired provisions – extending some permanently, while declining to restore others. “That’s not going to fly,” he said.

Even if Wyden and Republicans do negotiate over amendments, it is far from clear that Democrats would allow a vote on the medical device tax.

Wyden said on the Senate floor on Thursday that he would discuss amendments relevant to the tax extenders bill.

He blocked attempts to attach a medical device tax repeal when the Finance Committee considered the extenders package, arguing that it wasn’t among the tax provisions that have expired or are set to expire.

Wyden, who backed repeal of the tax last year, added this week that he planned to take a similar approach when the package was on the Senate floor.
