Senate Dems plan bank reform procedural vote -aide

WASHINGTON, April 21 (Reuters) - Senate Democratic leaders plan to seek a key procedural vote on financial reform legislation on Thursday and are aiming for a final vote on Monday, a senior Democratic aide said on Wednesday.

At the same time, leaders are awaiting the outcome of continued negotiations over the bill toward a possible bipartisan compromise, said the senior aide and other Senate staffers involved in the closed-door talks.

Democratic leaders plan to call for a vote to try to block a Republican filibuster that could prevent formal debate from starting on the bill. Sixty votes are needed to invoke "cloture" blocking a filibuster.

Democrats control only 59 Senate votes and would need at least one Republican vote for cloture to proceed. (Reporting by Kevin Drawbaugh; Editing by Dan Grebler)
