The Senate cast sufficient votes on Thursday to give final approval to the most sweeping overhaul of financial regulation in decades.

Voting continued, but passage was expected since Democrats backing the bill control more than the 50 votes needed.

The 2,300-page bill would slap tough new rules on the banking industry, set up a new government process for dismantling troubled financial firms, and create a government consumer watchdog to regulate mortgages and credit cards.
