Senate rejects wrapping up debate on Wall St bill

WASHINGTON, May 19 (Reuters) - Democrats in the U.S. Senate failed to muster enough votes to wrap up debate on a sweeping overhaul of U.S. financial regulations -- a surprise setback to one of President Barack Obama's top domestic priorities.

Two Democrats joined 39 Republicans to deny the Democrats the 60 votes they needed in the 100-seat chamber to wrap up debate on the bill and move toward final passage.
