New York State Attorney General Andrew Cuomo filed a motion Monday asking former Merrill Lynch Chief Executive John Thain to provide more information about bonuses paid out on the eve of the bank's merger with Bank of America last year.

Cuomo's office alleges that Thain is not answering the questions under instructions from Bank of America , and as a result, the bank is interfering with its investigation of the bonus payments.

In a deposition last week, Thain refused to answer questions about how the bonuses were determined for certain individuals, citing instructions from Bank of America attorneys.
