"The appropriations process is not the place to jam through ideological poison pill riders," Schumer, expected to be the next Senate Democratic leader, told reporters during a conference call.

He added if Republicans try to attach "poison pill riders" to the appropriations bills, "we're just not going to let the process go forward."

His comments come after a GOP amendment on buying heavy water from Iran temporarily threw the energy and water bill into limbo, with Democrats repeatedly blocking the legislation.

Schumer said that the Republican leader "has a responsibility" to help defeat controversial GOP amendments, either by not letting them move forward or voting against them.

"We're not obstructing," he added when asked about the Democratic strategy. "They'd be obstructing if they allow poison pill riders to poison the process."

The Senate is currently debating a merged Transportation, Housing and Urban Development and military construction and Veterans Affairs bill.

So far, leadership has been able to avoid controversial amendments to the normally uncontroversial bill and is hoping to finish work on the legislation this week.

"If the lobbyists and their Republican friends think they'll get away with using government funding bills ... they are very, very wrong," she added.
