The embers of the US Congress have started to revise an agreement on the US financial reforms after the Republicans objected to apply tax on the large financial institution. After a 19-hour long negotiation between House and the Senate legislators on Thursday, the democrats were very much sure that their bill would pass both of the chambers.

But Scott Brown, the Republican Senator now has said that he will withdraw his support if his requirements over the tax issues are not fulfilled. The bill would bring the largest change to the financial regulation of US in these decades.

The reforms are made in intent to impose a strict limit to the ability of the banks for taking risky bets on the markets.

This legislation has been expected to pass the both chambers of Congress in this week and the US president Barack Obama to sign it into law by 4th July.

But except Mr. Scott Brown the Democrats have not any other Republican votes for the bill in the Senate.

Mr. Brown cleared this on Tuesday that he would no longer reverse the bill if his concerns over the tax on the large financial institutions were not addressed.
