Senate Democrats are considering abandoning their attempt to include controversial International Monetary Fund reforms in a Ukraine aid and Russia sanctions bill.
House Republicans have put up firm resistance to approving the 2010 IMF reform, which may prove successful in getting the language dropped.
The Senate advanced the Ukraine bill on a 78 to 17 vote on Monday, setting up a final passage vote as early as Wednesday.
Meanwhile, the House Foreign Affairs Committee on Tuesday approved in a bipartisan voice vote legislation that does not contain the IMF language that the White House is pushing for. That bill could see a floor vote in the House later this week.

"[T]his bill cannot pass the House or become law in its current form — it must be amended," McConnell said.
Republicans have signaled in the past they could be open to trading the IMF reforms for a one-year delay in Internal Revenue Service regulations on tax-exempt political groups.
